I made a chick condo! lol I took some old light windows, a couple wood crates, some window insulation plastic for the roof (it's pretty high so they won't get out) and lots and lots of duct tape and bit of cardboard. lol they are so happy! I built onto the booder pen i had. It is too cold for them yet outside and we got a big snowstorm on the way again but these chicks were way too crowded. now they are so happy and up and down the repurposed shelf for a ladder etc.
