I have 3 Serama chicks about 3 weeks old. Someone gave me (stupid me!) 4 Japanese bantams about the same age. I put them in a seperate brooder, but fairly near my Seramas. 2 of the Japs started stretching their necks up a bit and seemed to be gasping for breath, opening their beaks with each breath. After a few days, one died then the next night, the 2nd one died. I gave back the other 2. Now, one of my little Serama chicks has started gasping this evening. ?? I have Poly Vi Sol, and have read on here some suggest it, but I have forgotten how to give it. Do you just drop a drop into their beaks, or mix it into their water, or what? And if so, at what ratio? Any other suggestions?
