So, I got this coop off of KSL from a guy who sold it to me for $50. I got it about 3 years ago. When winter hit this year I noticed that my chickens might frostbite, some broken toes, and are getting cold at night. I have a heat lamp in there and wired floor. I also took down there 2 by 4 board because the were pooping on it and made some modifications that I thought would help. But now I'm regretting it. I only have two. Do you think The coop is ok or do I need to fix it.
