I put 4 of Jody's EE's in the egg carton, and all 4 hatched. The only problem I found is that they chicks didnt get out of their shells....they just sat there for hours. I finally dumped them out, because I didnt want them getting stuck. I have another hatch happening this weekend, brahmas. I will do the same with them and see if I get as good a percentage hatching as I did with Jody's. All have candled good up to this point.
