Funny story,
My FIL has a pullet and 2 cockerels, one of the cockerels goes missing, he's sad because he liked that one better than the remaining. A week or so later his pullet goes broody on about 3 eggs (she has only been laying for a few weeks LOL). He is still sad that his favorite cockerel is missing without a trace. He randomly sees chicken tracks around the yard in the snow when he doesnt let his birds out, follows them - Lo and Behold he is a she and is sitting on about 10 eggs. so now he has 2 pullets, both broody. fast forward a week. He is telling me that he has been seeing his cockerel sleeping in the laying box with his broody pullet. HMmmmm so FIL are you as sure about this one being a boy as the other boy you had?? thats a good question
He brings me a picture of them 'sleeping' together. He now has 3 broody pullets, and they could be sitting on infertile eggs, but there is a small chance that a couple could be fertile. He started with 5 birds and lost 2 to predator a couple weeks before the first one went broody
i have no idea if any were cockerels or if all 5 were pullets.
I told him to check (candle) the eggs tonight
i may have to teach him how to break a broody tomorrow
