Can't tell you how much I appreciate all the feedback! I have another post in the breeders and hatchery section so I am going to see if I can pull together all the info and get an order together!
I think my neighbors will be OK with a little noise, but you are right kipper - roos are out of the question. And if I have to, I can share some eggs. I was talking with one neighbor today, and shortly after I mentioned the chickens again, she asked if they attract rats. Do they? Never heard of that.
And my mother started telling me of the horrors of mites. So I did a little reading on that and it seems like an issue that is controllable.
With our allocated space of 400 square feet (that is a conservative estimate) for the coop and run, I am starting to wonder if 12 chicks is too many. The run area is about half shade and half sun, with a couple of large pine trees in the area. Not a lot of vegetation. I would love to get 12, but only if they birds are going to be happy and healthy in that space.
And thanks for the clarification on the EEs!
