Hi all I've had a broody hen sneak up on me! We've had chickens for several years now and this is our 1st broody (since I was a kid living on a farm anyway, and I don't remember much from back then). She is a 1 year old japanese bantam. She has been sitting for 14 days now. She set up 'shop' under the floor of the coop, which has plenty of room and ventilation, but access to her is not possible, so I fenced off her area last week. I can't see how many eggs she has, but there are at least 12 under her. Before I fenced her area off my other hens were sneaking in there and laying their eggs in her nest. So that means the eggs under her are different 'ages'... what will happen to the younger eggs, will they die? Could/should I incubate them? Will she continue to sit if some hatch and some don't? Also, she has bantam eggs and full sized eggs under her. We have 3 bantam roosters and our hens are a mixture of bantams and full sized breeds. I'm sorry if this is a dumb question, but can the bantam roos fertilize the full-sized hens' eggs? I do see them mating but wondered what will hatch from those eggs? Just curious Yikes, so I hope I didn't mess up this whole experience by not fencing her off sooner. I am hoping some of her eggs hatch. If not, we have a few chicks on hold at a friends farm to give her to raise.
