Ok so we wanted to raise some chicks but didn't know how to go about get my hens to brood. ( I should have looked on here first, I know...)Someone told me to just leave some eggs in the box and one will lay on them. So this has happened but now I have been reading posts and see that some have been candling the eggs.... is this to ensure they are laying on fertile ones?? Is it necessary to do it?? AND if none of these are fertile can I take them out from under her without harming her and if some are fertile and some are not what should I do with the "bad" ones leave them till the good ones hatch or take them out?? I have noticed too that when she got down to take a walk to the feeder another hen jumped up and laid on the eggs is this normal?? Also not all the eggs belong to the same hen. Will any of this matter???
