We are new to this as well. First year for us, and we are trying to get the coop weather-and predator-proofed. I have a bunch of pictures on this thread. Looks like you have a nice variety to start with, and yeah chicken math has struck you! We have 2 leghorns, 2 SLW, 2 amber links and 2 NHRs. The last 4 are pullets (girls) and the first 4 are 50/50 chance. Hopefully not more than one well behaved rooster.
We are not insulating our coop, other than an outer wall and an inner wall. From what I've read, it's not necessary to insulate, and I've read that some don't use heat lamps even in negative double digits. People who've use heat lamps have had some fires, so I'm not going to use one.
You probably have more than enough ventilation, and that reminds me I need to incorporate one in my coop.
Runs----------in the winter-----some chickens hate the snow, others don't mind so much.
You do have easy access inside the coop for cleaning? I am making sure of that. If there is not much access, then the necessary cleaning won't get done. Can't wait for our girls to lay some eggs! But it realistically won't happen until August, that'd make them about 20 weeks old.
