I have had 3 Black Copper Hatches over the last month. The first 18 days, all the eggs were incubated in a Brinsea Eco 20 at a temperature of 100.5 and 35% humidity. They were than hatched in a Hovabator at 100.5 degrees and 65% humidity. The chicks have hatched on the Day 20 in all cases. The eggs were sourced locally and were never more than 5 days old. Parents came from a mail order hatchery. Out of 40 eggs, 31 hatched and 12 of them have had their outer toe fused with the middle toe on both feet. In some cases, the middle toe was curled. All these chicks had the webbing clipped between the toes by 4 days and are active and healthy at day I am trying to figure out why this toe issue has been a problem. I have never had this issue before in this equipment. Do you think it is the genetics of the birds or the temperature? Thanks in advance.
