Please help, my 16 week old barnavelder is sat on my knee as we speak. She is not eating, her breast bone is protuding. She has a muck bum but not sure what the poo is like so should find out today. She is a fluffed up with her head down asleep. She normaly runs away when you try & catch her. I dont have any antibiotics only some metnoclopamide but not sure if i should use that.what should i feed her???? All my 25 chickens have been injected for mereks, they get treated 3 times a year with flubenvet and have all had coccid treatment too so im at a loss
