For the last couple of days we have been in our typical weird weather pattern really cool in the morning and really warm in the afternoon. My Brown leghorn has just not been herself lately. She hasn't laid an egg in over a month. I first thought it was because the other hens were laying larger more colorful eggs. Then I thought it was the lack of natural sunlight due to the season change. But the other hens are still laying. This AM I noticed she did not come after the cracked corn like she normally does. She runs from me rather than too me. When I would come to refill their feeders she use to come to me and try yo eat the feed out of the bucket. She doesn't look like she's molting . She looks interested in food , pecks the ground and such but doesn't jump in with the rest of the hens. She stands in a corner with her head tucked under her wing. COuld it be the weather, is she egg bound , any ideas? DO I need to seperate her. I haven't noticed any bloody diarhea. My chickens have been healthy I clean their coop weekly if not more often Somebody help?
