Hey everyone. I was curious what everyone uses for grow out pens. I have 2 chicks which are about a month old now. I have been using a extra large dog crate as a brooder, its been working good, the 2 older chicks are in their awkward feathers growing out everywhere stage and soon I would like to move them to something larger, as lately they have been racing back and forth in the cage, and just all around getting wild. I am curious how much space these birds should have, as I do not want to take them outside yet, still a lot of snow where I am and a lot of cold nights ahead. I was thinking I could put them in my dirt floor basement. its a solid 20 degrees cooler then the rest of the house so it would give them a slight cold hardening. once the spring sun has melted the snow and started growing grass I plan on moving the pen outdoors onto the yard, near the chicken run, so my older girls can get use to the new comers.
