I have 3 BO and 3 Barred Rocks. One of my BO has been disappearing and I thought she was gone for good last night when she didn't return to the coop at dusk. I checked the yard last night and early this am and didn't see her. She did reappear in the coop mid morning and was sitting with the other 2 BO. Then she disappeared again and I found her late this evening sitting in a window well against the house. When I picked her up to put her in the coop I found 18 eggs !!! I am worried about her because the temps were in the upper 80's w/ high humidity today and will continue for a few more days at least. What do I need to do? What do I need to watch her for? Are the others likely to join her? AHHHHHHH !!!
