Occasionally I see my 3 day old chick stretch it's neck and open its beak like it is choking. Other than that it is drinking and eating fine except the mother hen seems like she is teaching the chick to eat the pine shavings. She will pick the shavings up then drop it for the chick and sometimes even eat it herself. I was thinking of moving them onto paper towels but there are still four eggs unhatched. Does the chick have an impacted crop? If so, what do I do?
