I have a dozen chicks that are now turning 3 weeks old that i purchased from tractor supply. We have recently moved to the country and had already built a coop and run. I cannot tell you how much i am enjoying my time taking care of and interacting with these chicks. Well today i was in the local feed store and there they were...RIR and another bin of black chicks...i couldnt help myself i got 3 of each. I realize im addicted lol. Now when can i put these chicks all together? Or do i have to build another coop? And let me just say...thank god for this site as a newby this has been a lifesavor!!!
