I have two Yokohama, and two Japanese bantam chicks I got from my feed store. They will be two weeks old tomorrow. However, the two Yokohama chicks are doing a sneezing type of thing. They were in a large fish tank, but they were outgrowing it. So today, I put them in a larger cage, so they have more room. Its a wire cage, so I am guessing they might be cold? I do have a heat lamp in there, but they are not all huddled around it like there cold. They seem to okay. They do a little sneeze thing, and jerk their head. But there both eating and drinking. Am I over reacting, or should I put them in their old tank, where there warmer? Thanks!
