My husband and I are new to chicken ownership and need some advice. We have nine 9 week old chicks that were given to us by a neighbor. We went through the coop training process with them and after free ranging most of the day they will go back in the coop on their own as the sun goes down. We will be getting 11 more chicks in about three weeks and we plan on having them all in the same coop as the others once they are old enough to make the transition. The question is, how do we coop train the newbies when the coop is already occupied? I will post pictures of our set up to go along with this, but if we keep them in a pen or dog kennel inside the run portion of the coop for a week, will that be sufficient to teach them the coop is "home?" Will they just follow the other hens up into the coop? Just as a side note, we will do the play pen method of introducing them to the flock before we start coop training them. Thank you in advance for any help!
