A little over three weeks ago I bought 8 fertilized eggs to put under my 2 broody hens. Candled them, all looked good. Then the heat wave set in. Had about two weeks of temps over 100. I'm sure in the coop it was even hotter. Thought I'd just see what happens. The chicks hatched a couple days ago, but none of them survived more than a day. We're the eggs too hot, too hot after they hatched, both? All chicks were found outside of the nest, one was still under one of the chickens. One was eaten by one of the non-broody chickens. Not sure if it was dead or alive before she started to eat it. My first time doing this, but guessing our 100+ degree days is too hot for hatching right now. Any input would be appreciated. Would love to try this again when the weather cools.
