Hi all, We are having a bit of trouble with our 9wk old sussex. Over the past few weeks we have been treating our chickens for coccidiosis. We initially used Amprolium 200, but found that after we finished the dosage, the chickens didn't appear to be better. Last Monday we started a dosage of Baycox. This really clearly made her better but after finishing the dosage on Saturday, she seems to be deteriorating again. One of the main symptoms that our girl has is that her feathers, especially on her wings and down the front of her neck, are going hard and crispy to a certain extent. I have included some pictures below. If anybody has any advice about something else this feathering could have something to do with it would be greatly appreciated.
