Im so bad I even encourage them to flap up to the edge of the brooder to perch there, looking around. I only covered the brooder with wire when I am not home and the door to the "nursery" is open. (Cats.)
I would walk in to the room, see a chick on the floor, and cheer the chick on! "Come on, you got out, get back in again!"
And they do.
Easy to clean up Evidence of Chick Explorations.
When a chick steps from the edge of the brooder onto your hand - such trust! - your heart will nearly explode.
That's why I didn't cover the brooder bin.
