I'm sorry if this is a dumb question, but I have one last chick left in my hatcher. All of the others have been moved to the brooder. Not only was it the last to hatch, but it has hatched four days late and came out of the shell with what looks like just a little bit of yolk left to absorb... Now... the weird part, at least to me, is that I haven't heard the chick make a single sound. At least from my limited past experience, I get at least a few peeps from the babies. They might peep before they externally pip, peep randomly while they hatch, peep while they dry off in the hatcher, or peep once they get to the brooder. At some point, they make a little bit of noise. NOT this one. Stone cold silence. I could whistle or tap on the incubator and get a real rise out of the other babies, not this one. I see it breathing quite heavily....appears exhausted. Does this happen sometimes, or should I be worried?
