Hey all. I have buff Orpington hen who is just disappearing every night . She comes back in the morning but is not really sticking to the rest of the flock. I wait until it's late to lock the rest in but can't leave the coop unlocked all night. I did get a soft egg from her a week ago and a friend of mine told me she'd be molting but I'don't know. Is anyone familiar with this behavior? And is there anything I can do to get her in.
