I currently have 24 RIR, nearly a year old. They really have worked out wonderfully and I again thank you all for your wisdom. Never would I have tried chickens without the help of this forum. I would like to add some different kinds of chickens to the flock. I am particularly enamored with EE's. Love the idea of colored eggs- can't help myself! I understand that chicks have to be kept apart from the flock -both because of age and quarantine issues. My question is -when can they be combined in the same coop? I will have to add on to accomplish this and I thought I would build the new section and not take down the wall between the two parts of the coop until they were ready to mingle. Does this sound doable?
