Lately I've been wanting to breed and hatch my chickens at home. Well, not now; I wanted to wait until spring. With usual cold winters here, I don't want to risk the chicks getting some sicknesses. I'm very excited and have starting planning. Some hens are good clucks, but others, will just eat the egg they sit on (for some odd reason. Usually those leghorns!) We have three separate rooms; one for storage, one for the laying hens, and the last, a spare. I want to use the spare room and house about 3 hens, each on 3 eggs. Hopefully they don't bother each other. One of my relatives is offering German Giant eggs also. We told her we'd take some in the spring, and hatch them for her, and some for us. Would there be downfalls to mix-breed chickens? Should bigger birds stay with bigger, and small with small; stuff like that. Like, would any weaknesses be in the mixed bird that a person doesn't want? Would anything harm the chicken? Would anyone have any tips or pointers that would help me get the right idea? Guess I'm over-anxious and want to get started! Thank you.
