I have a questions about fertility...
I have 1 Partridge pair, 1 buff pair, a white pen with 2 males & 1 female, and a BBS pen with 4 females & 2 males.
So for the past 3 weeks, they have been laying, but only the Partridge eggs are fertile. They eat the same food, so could all 4 cockerels be infertile? They are all the same age from the same hatch. I just hatched partridge chicks, and so far, up to last week, non of the other varieties eggs are fertile...
Any advice? They are eating 21% protein feed. And have vitamins in the water 24/7 with a little vinegar.
You never said how old they are. What are their cushions like? If they are quite large, you will have to cut them back. If they are just average, then I'd guess your cockerels are too young. I have a cockerel that has a very large cushion and there is NO way he will ever breed on his own without being cut back. Since I'm showing him right now, I'm simply doing AI with him. I have a couple of other cockerels and they are hatchery stock-- they are thrown in with my layers right now. They don't have much of a cushion and they are breeding machines and are able to fertilize eggs. (I'm not incubating their eggs, just notice our eating eggs are fertile.)
