Hi, I have 8 6 or 7 week old chicks and 2 1 or 2 day old chicks, this is my first flock. I have a old coop in my yard from the previous home owners, it is small with only about 4 roosts in it, and it is about 6" off of the bare ground with no floor what so ever. My Hubby was going to add a few nesting boxes to the side of this , but I have started wondering if it needs to have a floor. I was going to put my chicks (the older ones) out into the coop and run this weekend, but it's supposed to get down to 40 degrees at night, there is a heat lamp out there for them, but not sure if they would get cold anyways without a floor and the wind blowing in. Help!! Thanks, Jenn
