Hi fellow chook lovers I have a backyard flock of 11 chickens of mixed breeds. My black orpington (approx 18 mths old) has been steadily losing weight. I wormed her about 6 weeks ago, but no improvement. I noticed that she has undigested grains in her poo. She's got runny poo stained feathers around her bum/vent. She's not laying. Her comb has changed colour from red to purple - so I think she's anemic. She seems listless and depressed at times, although she was happily scratching about today. I noticed she's growing new feathers (it's autumn and most of the flock are moulting at the moment) She still has a great appetite and is drinking well. None of my other chooks are exhibiting this condition. Please let me know if what's ailing her and what type of tonic I can give to help her recover. Thanks so much in advance!
