I have a little silkie chick that is a week old. She doesn't seem to be quite as active as the other 12 chicks. She is moving and looks like she may be eating some--but the other chicks run to the food bowl while she stands in the corner most of the time. She looks like she might be having slightly labored breathing. Beak isn't open but her body just seems to shake a little more than the rest. Of course it's soooo hard to tell on them this age. The fact that she isn't running to the food when the others are, is kind of weird to me. What do you think?
