11 mo old coronation susses roo tired looking. is eating but not good color. I have not seen his poop yet. He looks rough the last 8-9 weeks. Comb and waddles are very pale. He will not breed(you know there is a problem if not breeding) and tail down. I have wormed two times in the last 8 weeks thinking maybe a parisite and also tried antibotic for 10 days after that a round of sulmet. I stopped all meds 3 weeks ago and started on vitimans in the water. Suggestions??
