When feeding I noticed that 2 of my Bantam chicks were kinda off by themselves but did finally come to eat. After feeding everyone I went back to check them and picked 1 up and felt her, she had eaten and was acting better, so I put her back and reminded myself to check them in morning. They were fine next morning, so I checked them again last night and they still are acting like they don't feel good. They will eat/drink then go off by themselves and sleep. I got them out and 1 chick is wheezing. I decided to bring them in and put them in a cage in the house. I put Teramiacin (spelling?) in their water and fresh food. I just switched them to layer 2 days ago as they are 3 months old. Should I put them back on chick starter? Is there anything else I should do? I checked on them and they are sleeping but I can hear rasping/wheezing while they sleep.
