Our broody hen has been sitting in 4 eggs for the last 15-0 days. This week two of the eggs completely disappeare . Yesterday one of the remaining eggs started piping through. This morning i found the chick in the middle of the coop but its not fully develooed yet. Its eyes arent open and its still in egg fetal position . Its still breathing so i out it under a geat lamp. What should i do? Any chance of it surviving?
