Gaz131 - Did I understand you correctly? Did you say that the higher temperatures tend to kill the cockerels? I wonder if there's something to that... Because come to think of it, my neighbor hatched some sex-link eggs, and got about 50/50 ratio on these eggs at 99F. I've hatched these same eggs, at 101F, and gotten a male/female ratio of: 5:13, 8:9, and 2:17! Not to be hard-hearted, but I'd prefer that the cockerels never hatch... I'm going to go research this!!!
