Hi. I am introducing two new hens to my small flock of five. I’ve done the “look but don’t touch” method, then let them mingle but kept access to the dog kennel I had them in so they could get away from the others. Now they are mingling without access to the kennel, just staying there at night. I think I’m ready to take the kennel out of the run. My question is how do I get the new hens to go into the coop at night which I close after the girls are settled in. The coop is plenty big enough for two more.
