Make sure the brooder is cleaned our really well. No old bedding or anything. The feeders and waterers need to be scrubbed. Anything the sick chick came into contact with needs to be washed. If it was a respiratory disease, then it's probably contagious. Electrolytes would be a good idea, but if it was respiratory, Duramycin won't help. It wouldn't hurt to give just in case, though.
