I want to start letting the little ones go outside for an hour or say a day. Feel the grass, chase bugs, eat dirt- you know- kid stuff. but i am racking my brain for something i could use to contain them that would be portable and easy to store/ put up/ take down when not in use. I do not want this thing in my backyard perminently, only when the babies are out. so to get an idea of what i was thinking- i was going to buy a used child's play pen and just flip it over and put the chicks inside. the downfall to this would be 1) the bottom of the playpen would nlock the sunlight from getting to the babies and keeping them warm 2) it would be really hard to grab the babies to take them out. I think id have to crawl into it. (sheesh!) what do you use as temporary chick-keep-in-ers?
