Can't say exactly but I can tell you they fit through at 1 week old. The sides of my brooder area are all 1/2" hardware cloth, the top is 2x4 welded wire. I went to close up 20 minutes ago and Little Miss Daredevil * flew up to the top of the feeder from "food and water stand" level then straight up through the top!!Also, how long before they won’t be able to squeeze through 2x4 welded wire?


Here they are yesterday getting ready to move, wish I had a movie of us trying to get them all back in the shipping box, Keystone Cops event, and in the brooder area. Sorry no pictures that show the top.




Video. They weren't too interested in going into the brooder area, scary new place. Voice is DD2, she turned 23 today.
* the one that was flying from the top of the cave to the top of the food and water in the cardboard box in the house
