My once sweet and docile 5 month old Black Australorp hen is now a ranging B!@#$%. My sweet girl has been acting so strange. I noticed she is constantly making noise. Not a pleasant chicken noise but a reputative chirp I guess is the right word? She also has lost interested in food, but she still eats if that make sense. For example when I bring out the tray of greens and treats she eats sparingly where as before she went to town with the others. When a would break out the black soldier fly larvae she would gobble them up now she just stairs at them and walks away. At night when she goes to bed I was able to give her a message and pet her. Now she aggressively pecks my hands and the other girls There are 3 other hens in her coop all the same age. I've noticed her crop is empty at night where the other girls have a nice full crops. This AM I notice so many feathers in the sleeping area. While I was sitting with the girls at treat time I noticed her feathers fall off of her, She has no bald areas? I don't believe she is laying either. I can tell she is lighter as well, but still has a healthy look to her. She is active and takes in some food and fluids. All the poop in the coop and run look normal. I have 4 watering stations and 5 areas to take in crumble and peck and scratch layer feed. Up until about two weeks ago I was fermenting food, but stop due the fact I felt as if I was throwing most of it way at the end of the day. I put ACV in their water and change it every other day. She has a nice large coop and has ample room in the run. When I get home from work they have access to the entire yard until they go to bed. Any ideas?
