Just recently like in the last 2-3days we have what would seem like a broody hen. She's showing all the signs, growling, she's puffed out when I even get near her she's nipping when I try to get the eggs. And she goes right back to the nest if I take her out. She will sit in there for hours. So long in fact I had 2 hens in one box. Here's the thing though after sitting in there for hours she will lay an egg sit there until I take it out then she'll get down later never to return again. Is she just really private or what? And then we have a completely different hen that isn't roosting the past 2 nights. They are about 7 months old and clearly know to roost. She has been laying on the coop floor over in the corner. She's not hurt or anything like that that I can see and she's not the weakest one either. Should I be worried or is this all normal for chicks? Our Hens are all Buff Orps? Please someone give me advice.
