I have a 3 year old Black Australorp hen that has not come out of the nesting box all day. It is almost dark now and while the other hens are on the roost she is still in the nesting box. I can force her to come out and when I do she looks fine but a little frustrated with me for making her move. I have never had a hen go broody before and like I said she is 3 years old. Do you think it is just that she is broody or is there something wrong? I have read on here about eggs being stuck and such but I would not have a clue what to look for. Can someone help?
