hello! today we are bringing home 3 new either 10 or 14 week old chickens. we will only have one 17 week old RIR to introduce them to. she has been at the bottom of the pecking order (we are returning 2 roosters today). my question is should we just let all the chickens out to free range? or should we keep the newbies in the coop for awhile so they know where "home" is? should we keep the RIR in the coop/run with them? thanks!!
