18 mo. old Australorp. Appears to be eating fine, drinking fine, pooping fine. Spends much of the time sitting on the coop/run floor. Will get up and run away if I approach. Has pale, shrunken comb, pale ear lobes, white tips on the feathers that came in on her head. She's currently molting, but not acting typical of a molting hen. Upon examining her today her vent area appears fine. However, she had some scabs on her chest where it appeared she had pulled some feathers out. I pulled one scab off and it was a little pussey under it. It feels like there is a puss pocket the size of a quarter on her chest. I tried putting a warm compress on her and seeing if I could get anything out but couldn't. I think I need to put her on antibiotics. I have 250 mg capsules of amoxicillan OR tetracycline (normal stuff you put in water). I'm thinking I should go with the amoxicillan but don't know how to administer it or what dosage to use. There's nothing else available in our local feed stores. Please help me figure this out!!! Thanks
