Hi there! Just got my first two chicks last Friday. One seems to be a bit spunkier than the other. The more relaxed one is starting to lay down, and puffs up when she does. It looks like she's incubating. If bothered by the other one, she sort of rolls on her side and kicks her leg out. It seems like she falls asleep at the drop of a hat. I've also noticed that she breathes a bit heavier than the other, too. She does play, she's just not as high-strung as her sister. Is she just being a baby, or could there be something wrong? Thanks!
