I intend to set eggs to hatch. I have some hens that are 5 mos. old CM's laying nice sized eggs and some hens 10 mos old Dels. And some I'm sure are at least a year. Dels also. Should I expect any problems hatching these eggs? I'm aware the older hens eggs will be fine. I will be using a Hova Bator. I've used it before and only used the older hens eggs. I got 6 out of 13.
