I have two broody hens who have managed to hatch 3 chicks out of 7 eggs. All seems fine, they make great tag team mothers. The three chicks were doing just fine when I checked them this afternoon. I went back out to check on them and one of the little chicks was laying in the middle of the coop away from the broodies on its side, still soft but not alive. Is it normal for a chick to be found dead outside of the nest?
