We had to get rid of an accidental rooster. So, because there was a chicken for each of our children we had to get a replacement. We found a breeder willing to hold on to chicks for a few weeks to be sure of sex. (and cuckoo marans are supposed to be easier to tell) Anyway, we are getting two so that they have each other and won't be lonely. How long until i should start to introduce the two groups of birds. (our others are 12 weeks old, these will be 3) Should I let them check each other out a little each day with supervision? Should I keep them totally seperate for a little while because the new ones were raised with many chickens and could introduce something to mine? When they are ready we were thinking about keeping them in the run with a wire enclosure to allow all of them to adapt, but for how long? It is HOT here! so they have been used to the heat, but at three weeks, will they need warmth at night if there is only two of them? Our nights are 70's If they can be in the same area and just enclosed in the coop will that be sufficient for heat? (coop is insulated and that would make six in there) Wow! I do need help, all these questions and they are coming today!!!!!
