Yes! I was really excited when they first discovered the coop. The female is the more outgoing and she went in first, and jumped up on the roosts (middle of the day) and walked back and forth on them, chattering excitedly. The male is more reserved and peered in the door but was reluctant to join her. That night she decided it was a good place to sleep but he wouldn't go in. She went over and talked to him earnestly for awhile and after that they both walked into the coop and jumped up on the roosts. It was really amazing watching the communication between them.
Since then, she has gone in voluntarily (through the chicken door) every night. He will go into the coop via the people door but has only gone in the chicken door twice (to roost - by day he is in and out of it all the time to eat). He really would prefer to sleep outside, and only goes in when she really insists. However so far he sleeps on my chunnel which is only 4' high so after dark, when he is asleep, I pick him up and carry him in.
