So I have a small silkie chick that I have hatched. She was born weak and we didn't think she would make it. It's been a week and she is much improving but I think she has an infection. I have antibiotics but it only has directions to make a gallon. I can't use all that for just one baby chick. Can someone help me figure out the dose for 2 cups. The antibiotics are oxytetracycline. Thanks.
