I have a chicken it's about 2 years old and she just molted but it's taking a lot longer for her to recover. I've got her isolated from the other chickens and she's lost a lot of weight. She's been eating good and started putting on nice looking feathers but her comb doesn't look that great. She's drinking water and eating and walking around but she's kind of weak. Been feeding her scrambled eggs ,fly larve and regular chicken food. Any suggestions on how I can get her to put weight back on?
