Thank you all for your replies!
Sounds like everyone is doing pretty well so far!
We finally got our new coop built, by my husband, and it's pretty great! I loved our tiny one, but it wasn't nearly big enough for everyone we have. He did at least partially insulate our coop, but although we have a heat lamp (against my wishes) I don't plan on using it.
How are y'all doing on egg production? Since most of mine are just starting to lay, we are doing pretty well. Can't complain! It's been a blessing raising the chickens so far, although it was definitely a ton of work to begin with.
