Hey guys, long time no speak !

 

I've had a shocker of a breeding season and come across a new problem, one which I haven't seen or heard of before. Maybe someone can help.

 

 

I've had some 10 eggs from one hen over 2 rounds, and now a further 5 eggs from a second hen where the eggs are half empty.

 

 

The Eggs have what looks like a hardened yoke in the bottom, and the rest is empty. Not rotten or smelly etc, and no sign of being fertile either. Just a hard yellow rock in the bottom, taking up about 20-30% of the egg.

 

Now the eggs are NOT broken or punctured which would make more sense, and the eggs just wobble around in the concave, heavy end down.

 

 

The Hens are related (daughter for 10 eggs and mother for 5), but the Cock bird is the same in both cases. The Mother had bred successfully before (obviously), but the daughter and Cock haven't raised any chicks (only 2 fertile eggs = DIS over 4 rounds) after trying this pair this year and last.

 

Does anyone have any experience with this, or heard of this before ?

 

The birds appear healthy, and the same conditions have been used previously with successful breeding.

 

Help ?

Hi this usually happens when the shell is a bit thin and the egg dehydrates or even infertile eggs when they have been there a while. Make sure they have ample calcium of different types. Cheers Jenny
