I do believe you have. Good Job! 1x2 should keep most chicks in just fine.I bought 1"x2" welded wire. Much heavier gauge than hardware cloth and chicken wire, and (I THINK) openings small enough to keep out the major predators I am concerned about in our area. We don't have large snakes, and weasels are very rare. The things I have to be worried about are dogs, foxes, coyotes, possums, raccoons, hawks/owls. If we have any little chicks, we'll have to keep them elsewhere until they're bigger, or run a line of hardware cloth around the bottom of the pen. But I'm hoping I have made a usable, affordable selection.
