I have a 2 year old leghorn hen who began molting and refuses to go inside the coop at night. She instead sits on top of the chicken run (my girls generally free-range) until I get home (after dark) and am able to put her inside. I know it's a matter of time before a predator gets her and since I can't be home before dark it's hard to train/bribe her back to her old reliable ways. This has been going on for at least 2 weeks! I've checked for mites, mice, other bugs etc. There's no signs of the others harassing her at night. One of the others will follow the leghorn's suit every now and then but generally goes in on her own. Any ideas???????
