So it's getting colder outside at night nowadays. Im not sure if my chickens will be warm enough! I have three, one ameracauna( Miley), one aracauna(Glenn), and one cochin(jenni). They have a mainly wood coop,(it's half fence, half house) and it has a chicken wire front with a dog gate thing for me and them to get in and out of, and they have a perch, a rectangle box thing, and then they sleep on top of the box. Miss Miley has recently been sleeping inside the box(there's a towel in there) and I think she's been pretty warm. I'm worried about the other two because they're stubborn and don't like to be too close to each other! They have a fuzzy material seperating them from the fence and wind (ocasionally rain when it actually rains here in california!!) Could I put material on the outside of the box so that it would be warmer? this is the box with Glenn in it.
