That's exactly what I've been doing over the last week now that the chickies are out and about back in the yard. At night some will go in. The others I have to gather up and place inside - then close the door quickly. They'll figure it out eventually. Everyone does. I had to do this same thing with every new batch.
My formerly sick Roo that I nursed back to health wanted to follow me to my car this morning as I was leaving for my days activity. Crazy Roo.
