Lately my favorite girl mabel, a buff orpington has been shying away from the rest of the flock and spending hours!... I mean hours so far today it's been almost 7 hours in the nest. When I took the eggs out from under her she got very made and gets all puffed up! I've taken the eggs out from under her but she won't leave. Yesterday I physically picked her up out of the box, held her for a while and put her at the end of the run. She's healthy and all, just seems out-of-sorts....Is she broody? We don't have a Rooster so I don't have any fertilized eggs for her to sit onShould I get some, or will this end soon?
