Wyandottes are supposed to be good layers through the winter. My 7 hens were laying 6 eggs every day. There were always 4 in one nest box and 2 in the other. Suddenly on Oct 1, they dropped to 1 a day for 3 days, now I'm getting nothing. Any ideas on why? 1- they don't eat the layer feed; I've tried pellets and crumbles, but they seem to prefer waiting for the human food. I do give them back their egg shells, oyster shell, and black soldier flies 2- the smoke has made our days very short; "sunset" yesterday started around 3pm (just meaning that's when the sky started turning red). I'm in Colorado and realize that what I'm experiencing is nothing compared to the West coast. 3- should I look for snakes and rodents in the coop? The hens do regularly have a gray squirrel visit the run, but I've never seen him in the coop.
