I have a group of 7 bantams that are 11 to 12 weeks old in a cage inside the house. No bedding, linoleum floor. Eating chick starter/grower with a large sand bath. 2 days ago I began treating for Cocci with Sulmet. tomorrow I begin the 1/2 dose. 3 of the 7 are not looking good. They are not eating that I have seen, their crops are large and feel like a water balloon. If I try to massage,no matter how gently, the water starts to come up but it does start to go down after. I am not sure if it is just lack of food or something more. The Cocci is clearing up so what do I do about the crops? Please help, these are my babies and I don't want to lose them.
