I know this sounds like a stupid question, but I'm still just wondering -- I have 30 eggs in the incubator, I believe half or more are fertile (I don't know which ones are and aren't so I chucked them all in and see which ones grow), and I know which eggs belong to which hen due to one always (pretty much) laying purple tinted eggs, whilst the other lay regular coturnix eggs. The eggs [if they hatch] will probably hatch when I'm not home (such as if I'm at school or occupied by another task, but they'd still be supervised) it'd be hard to tell which chick belongs to which egg shell if they hatch at close times, if you get what I mean. When they grow up (If they hatch, hopefully ) and mature, and well, mating occurs, will they be able to tell apart their siblings from their friends? Or would incest occur? Because I'd like to try and separate them into breeding groups with a roo and two or more females. . . I know incest isn't the best for animals, hence why I want to try and avoid it. Thanks.
