My cousin and I have a chicken that has been sick for a while now.. we tried Tetroxy HCA and had no positive result, so someone from on here told us to try the Tylan 50 but to do it orally and the chicken seemed better while we had her inside, but since we have put her back out she is sneezing again. Anyone have a clue as to what we should do now? We are bringing her back inside now. Do we medicate her again? and if so which antibiotic should we use? I was thinking to bring her back in and see how she does after a few days of just being inside, but we are just clueless as to what to do.. If someone could please help us out. She has been off the antibiotics for 8 days now. Please HELP!!??..
