I thought I'd start with some background first. One of my chooks was broody and hadn't been laying for some weeks. It was recommended to us that we get ourselves some 'day old' chicks for our hen to adopt -- well, she has taken to them quite well and has been looking after them superbly. My question now is, how old should the chicks be before we introduce them to the rest of the flock? Currently they are separated in a different coop away from one of our laying chooks and the young rooster. We are planning on getting rid of the rooster, though not sure when at this stage. Our fear is the rooster will terrorise the chicks and possibly kill them.
