Hi group! This is my first group of chicks. I have a salmon faverolle (SP?) that is 3-4 days old and she is breathing heavy all the time.I noticed it being constant yesterday. No real gasping but not really moving around, tho she will still eat and walk around on occasion. I have separated her from the others and given her water with tetracycline. I also dosed the water for the rest of the girls because a few are breathing hard now too but they are acting normal. Is there anything else I can do? Do you think Tylan would be a better choice antibiotic? I am freaking out a little with this bring my first group of chicks. Thank for the advice!
