So I bought I incubator from Amazon 48 egg auto turn. Issues being I have 4 chicks out 3 have died. Chick 1 seemed to have genetic issues and appeared to have had a seizure under the brooding lamp and then kicked the bucket. Chick 2 was a strong actually be vocal chick but was found chest up under the lamp. Chick 3 still in incubator and seems to want out. Chick 4 was a tough one and didn't want to part with half the shell. After 36 hours I removed the shell and it die then and there. All chicks are hatching 24 to 72 hours past 21 days. 1st check and 4th both were grasping for air very labored breathing. I have a couple more that have pipped but nothing vocal from them yet.
