Why arent my goose eggs fertile?

[Insane poultry mama]

Hey yall! I have a male and a female african geese that are one year old. The female has been laying eggs and everyday i take them out to the baby pool and they breed. She's up to about ten eggs now and I've been saving them for her to incubate when she's done in a cooler with appropriate temperature and humidity. I started incubating some of the older ones cause she's taking a while to go broody and i wanted to get the most out of her production. When i cracked the really older ones they werent fertilized cause they didnt have the ring. Would older eggs not have the ring even if they did when they were fresh? It's been eight days since I started incubating the older eggs and im not seeing any veins. What's going on here? My gander has been breeding my goose every day and it looks like he's being successful. Any tips or ideas?

How old are the eggs before you started trying to incubate them?

 

[Insane poultry mama]

5 to 7 days old.

Is there a way to tell if a goose is infertile?

I don't have the knowledge in that area hopefully some goose experts can answer that. Sorry I can't be more helpful.

Are you 100% sure of what the actual temperature is in your incubator?
Do you have multiple tested thermometers in it?

Just to check the obvious: are you postive you have a male and a female? I have seen hens (chickens) appear to mate with other hens, and I have read that this can happen with other kinds of birds too.

If he's been vent sexed and you have personally seen that he has the correct organ, then obviously you do have a male and the problem is something different.

There are allot of reasons a male can have low T. I change my gaggles diet slowly as I head to breeding season.

To much soy in there diet can cause production of estrogen in male's and many feeds are high in soy protein. I cut soy by adding sprouted wheat to there diet about 2 months before breeding season.

Low. E levels in there feed will also not allow them to get there T levels up. I add a E supplement to the flocks feed along with B and A supplements about 45-60 days before the first egg drops.. slowly increasing then decreasing the E once laying season starts. The sprouted wheat dose help with the E's

Light also helps ganders to increase there T levels. Starting in January I start adding light to there barn in the morning. My laying season is usually end of February. Sunlight however is the best for them so they can get there D's so yep supplement a little D during this time so it balances with there active hours.

Heavyweight geese if you have my type of African have to be maintained at breeder weight. There undercarriage if there overweight can get in the way of reaching the target. So with mine I limit the corn they have access to.

Heavyweight African Dewlap geese are known for a lowered 40-60% fertility. The commercial African who are smaller dont have the same problems. By doing these things I have gotten to 80-90%.

Calcium increasing is given here by oyster shell free choice. Putting it in feed can also mess with the ganders health and T production.

Side note. Hens will breed hens. If there is no gander around they pretend breed to get there estrogen up so they can lay. The best way to make sure you have a gander is watch them breed. Is there a victory dance or display. During that display look fro the little tool still hanging out of his vent. The dance helps them pull it back in.
Also how many eggs are you getting from one hen a week more than 4 in 7 days you may have 2 girls

As for seeing a clear bulls eye in a goose egg due to the thick heavy yolk its not always as defined as a chicken egg. I look more for a large spot for fertilized eggs and a dot for ones that are only fertile not fertilized.
