My youngest chicks are now almost 6 weeks old and it really is time they get out of the office. Between them and Quincy, my special needs house chicken, the dander and dust is too much. Our office is the only "safe" place for them since the cats and dogs are way too interested in them. I just took the dog crate the little girls have been brooding in outside and placed it next to the run so they could all meet safely. The Big Girls are very intersted lol. I don't plan on letting the Little Girls out in the run till they are a little bigger, but I was wondering if they are old enough to stay outside at night safely locked in the run area in their dog crate? Our run is predator proof with 3 layers of buried fencing - chicken wire, small opening ranch fencing and then hardware cloth all nailed to the surrounding railroad ties. Even the gate is 3 layer covered with no opening at the bottom (blocked off with cement blocks. Plus it has a completely covered top (the upper deck). They haven't had a light on them in the house for over 2 weeks now and seem fine. We have been getting down to 50 or so at night and I could cover the crate with a light blanket for extra protection. Any comments or suggestions on the idea?
