hey guys I bought a group of pullets from tsc I posted pics either here or on the baby chicks section. One is super undersized like less than half the size of the others (they are two weeks old or so) and she has a clicking noise when she breathes. Im assuming its a respitory infection and the only thing I could find at tsc was powdered oxytetracylcine. Ive been giving her this at the rate of one Tablespoon per gallon of water. None of the other chicks in this brooder show symptoms at all but I added it to their water just in case for three days and have been giving it to her with a dropper three times a day ( I never see her drink from the fount so I wanted to make sure she got her fair share) shes not being bullied though she does get knocked around a bit because the others have outgrown her and are running/flying. She isn't getting worse but is making leaps at getting well either. Fast forward to sunday I bought 6 straight run bantams they were in their own box but the box was in the big brooder with the bigger girls, and the clicking chick until yesterday when I got the banty brooder set up, I was doing the brooder chores and noticed one of the bantams seemed more tired than the rest and was sitting directly under the heat lamp while the other moved about everywhere. she seemed to be breathing slightly hard so I picked her up and shes clicking I immediately gave her some of the oxytetracycline in a dropper as well as some electrolytes and probiotics. Is there a better antibiotic I should be using? this is the only one tsc had that even mentioned poultry and respitory disease on it so I figured it was better than nothing but if there is one that is better please do tell! sorry for the long winded post I just wanted to get the whole back story in!
