The goslings have hatched!

We have successfully incubated Uncle Waldo and Abigail’s first set of eggs!  Four goslings were set to hatch today, and they all made it out of the shell, although one needed a little help. One more will hatch in two days, we hope.

Two days ago I noticed when I candled their eggs that they had internally pipped into the air cell. Yesterday evening when I got home from work they had all started to externally pip through the shell:

The penciled-in cross shows where the air cell dipped down to:

This morning they had enlarged their pip holes quite a bit.

First one out!

It’s lonely being the first one out, so she cuddled around her sibling’s egg to take a nap while waiting:

They slowly worked their egg tooth around in a circle to create a hinge at the top of the blunt end of the egg:

This little guy just wasn’t making much progress so we gingerly began to crack away little bits of the eggshell.  I put him back in the incubator like this and he made the rest of the trip out by himself:

We made a video of one popping out of the shell:

Everyone is now snug in the brooder:

The two girls have the dark grey bills; the boys have pink bills.

Candling goose eggs with intact and detached air cells.

Here is a video I made to show what goose eggs with intact and detached air cells look like:

This is my first time hatching goslings with detached air cells, so I did quite a bit of research on how to manage this. Here is what I believe is the best process for trying to repair a damaged air cell:

First, wash the eggs with warm (not hot) water if they have been contaminated with a broken egg in the box. Otherwise, don’t wash them if possible.

Second, candle the eggs to inspect for hairline cracks. You can rub a little bit of wax over hairline cracks to seal them.

Third, store eggs upright with the large, blunt end facing up and the narrow end facing down in a cool room for 24 hours. This allows scattered air bubbles to move back up where they belong.

Fourth, put the eggs in the incubator upright, in a vertical position, as opposed to laying them horizontally as one normally does with goose eggs. Do not touch them for 48 hours. No turning!

Fifth, after 48 hours in the incubator, begin turning the eggs from side to side but keep them at a 45° angle upright. You want that air cell to reform at the top of the blunt end as the chorioallantoic membrane forms around the inside of the shell.

By day 15, the air cell may be resealed at the top. If so, you can move the egg into a more horizontal position, keeping the blunt end slightly elevated.

 

 

Incubation progress and dealing with detached air cells.

I’ve set up a second incubator full of Pilgrim goose eggs;

This has been my little surgery-recuperation spot, with a rocking chair, reading material and incubators close at hand.  Currently I am (finally) reading SJWs Always Lie, which I received as a birthday gift this year, as well as Storey’s Guide to Raising Turkeys, in anticipation of 15 Midget White poults due to arrive in June.

Also, Domestic Geese by Dr. Chris Ashton has been invaluable as I learn to hatch the notoriously challenging-to-incubate Pilgrims.

I purchased some extra Pilgrim eggs on eBay from a farm in Missouri.  Although the seller packaged them well, the post office seriously mishandled the box, crushing one side and breaking one of the eggs, which leaked all over.

The problem with this is that fertile eggs have an air cell within them that can be damaged if they are jarred and jostled too hard.  Though the remaining eleven eggs are not cracked, there’s little chance of them developing if the air cells are damaged.

Eleven eggs from another farm plus three from Abigail; our hope is to increase genetic diversity in our flock.

I have propped up the purchased eggs with the blunt end up in hopes of getting the air cells to repair themselves back at the top of the eggs.

Here is the progress on Abigail’s eggs that I put in the other incubator about 12 days ago:

You can see a well-formed and intact air cell at the top of the egg. The blood vessels in the developing chorioallantoic membrane are also visible.

It is still a longshot that we will actually be able to hatch any goslings, but so far everything is moving in the right direction with Abigail’s eggs.  Now that the weather is warming up, we have stopped collecting the eggs she is laying in hopes of enticing her to sit on a clutch and hatch them the old-fashioned way!

Pilgrim Gosling Hatch-a-Long

Pilgrim geese, as I’ve mentioned before, are “sex-linked”,  which means right from hatching you can tell the males from the females based on color. Here you can see Uncle Waldo and Abigail as newly hatched goslings:

Abigail is dark gray: Uncle Waldo is lighter grey with more yellow in his fuzz.

Here is Abigail today, standing next to a Rouen duck:

She has made a good-sized nest out of straw in the duck-n-goose house:

The ducks have been sneaking into her nest to drop some of their eggs.  But ducks seem to be a lot less picky than chickens; whereas the chickens will only lay in their nesting boxes, the ducks have been dropping their eggs any old place.

We have 4 duck breeds: our light weights are Indian Runners, our medium weights are Buffs and Crested Whites, and our heavy-weights are Rouens.  You can see how much bigger Abigail’s eggs are than the ducks’:

By way of comparison, here you can see an extra large chicken egg, one of the medium weight duck eggs, and the Pilgrim goose egg:

Because we are having a cold snap with temperatures well below freezing right now, Phil has been collecting Abigail’s eggs every day and storing them in a wire basket in the basement where it is about  60°F.   If they are kept cool but not cold, out of direct sunlight, and turned over every day, the eggs will stay viable for several weeks.

We had been thinking that next week when temperatures come back up, we would return Abigail’s eggs to her nest. But now I have decided to incubate four of them all the way through hatching and let Abigail lay a new clutch of eggs to sit on.   From what I have read, Pilgrim geese are not the most skilled at hatching their own eggs

One of my co-workers had a couple of egg incubators she wasn’t planning to use anymore, so she gave them to me.  The model I am using is a Lyon Turn-X by GQF:

This model allows me to control the temperature and humidity and has an automatic turner that rolls the eggs 180 degrees every hour so I don’t have to remember to turn them myself.

In 7 days we will candle the eggs, and if this clown…

…has been doing his job, we SHOULD see this:

If NOT, then we’ll see this:

Check back in seven days to learn how the Uncle Waldo saga ends!
