So i have a broodie silkie who really wants to be a mama i guess. She has been broodie for over 2 months. I have tried to stick eggs under her twice, but both batches have been infertile. I dont know if its cause the roo is too young (hes 8 months and he only has 6 hens laying atm) or if it was the fact that the wood shavings weren't deep enough to keep the eggs warm enough cause they seem alot warmer today since i added more shavings too the coop and nest boxes (the eggs where siting on the wood of the box cause the shavings where kicked out alot). This is batch 2 and its day 9 but i dont see anything in them. Should i leave them for another week, or take them from her. Also should i try more eggs under her or what?
