I would like to get a few maran eggs to put under a broody hen. I've never done this before, so I have a couple of questions and plenty more that I haven't even thought of. How do you know that a broody hen will stay broody and make a good mom? Should I wait until a specific hen goes broody? Like maybe the Light Brahma or the RIR? Or doesn't it really matter? I've got BOs too. Okay, so let's say that I've got the broody hen that I want. How many days do I have to get the eggs that I want to place under her to replace the golfballs or whatever that's under her? It will take more than 21 days for the replacements to hatch. Will she stay on them? Should she be separated from the other chooks at the beginning of this process? Don't know if it's best then or after the babies have hatched. Lots more questions to come. Thanks for your help.
