I've had good luck using a milk crate for a nesting box as well.
Gallo, I'm so happy to hear about your cat being found safely.
The chickens are doing fine, I put some extra straw in the coop, and the cold isn't bothering them at all. I've been using supplemental light, and I'm getting five or six eggs a day out of eight laying hens, which is pretty good. My plants seem to be handling the cold ok. The leaves on the passion fruit vine are a little cold nipped, but there doesn't seem to be any other damage to the vine, and that is the most delicate plant I have. My orange tree was still putting out new growth, which is now starting to yellow, which isn't terribly worrying, and it seems to be doing ok other than that.
In other news, I had my 'big' ultrasound, and I found out that I'm having a girl! I'm really excited, and also kind of nervous, because its going to be a a big change after 3 boys. Everything else looked really good as far as her development, which I was very happy and relieved to find out. Related to that, if anyone knows someone who needs boy clothes, size Newborn through 24 months, let me know. I just finished going through my baby clothes, and pulling out all the clothes that are just too boyish to put on a little girl.
