Hi. We recently lost 2 of our hens. They are RIRs. As most people know, RIRs don't et broody often and will abandon babies. Since we lost 2 hens, we were gonna buy an incubator and hatch about 5. Do I need to buy anyhting else? When can I put them with the older chickens? Do we quarantine them even though it's the hens eggs? How do I know if the egg is fertilized? Will the older chickens try to hurt them? Can they fit thru hog wire? where will we keep them after we get them out of the brooder? The older chicken free range, so we can't lock them in the coop. Then the older ones can't come and go. Will the older chikens protect them? HELP!!! I'll take any advice. Tell me everything I'll ever need to know!!! Thanks in advance!!! Oh yeah, and we do have a rooster.
