I have read a lot about introducing new chickens to an existing flock & moving chickens to a new coop. However my timing isn't great (or maybe it is) and I have a new coop/run (existing flock is still in the old coop) along with an existing flock and 4 new chicks. Please help...do I...? (A) Move the big girls into the new coop now & introduce the new ones in the new coop when they are ready to be moved outside? (B) Leave the existing chickens where they are for now, move the new chick to the new coop when the time comes & then when they are used to it move the big girls in? (C) Move the big girls into the new coop, the new ones into the old coop and then move the new girls into the new coop once they are used to living outside? Any advice is very much appreciated!!! Thanks!
