In the last 8 days we lost 7 chicks! 6 buckeyes and 1 Americana. The buckeyes were all in the same brooder but there were also other breeds in there which seem fine. I'm wondering if this is more common with Buckeyes (Maybe they are more sensitive to the elements?) or if this is just a fluke? They are about 3 weeks old I think. There is nothing obvious that I can see on them to indicate what happened. Any thoughts from someone with experience?
