I have just started to build on my chick coop. My run at the time is on 5X10 cage that I have split down the middle for 3 chicks on one side and 3 on the other. I have taken an old rabbit coop and have torn things off and am rebuilding new things on. I am almost done just some few nicks and nacks here I am going to insulate it with heavy plastic. Not sure what its used for bought it at a home building place. Going to cover the entire coop for warmth for the chicks. I wont be able to use heating lamps due to where its located. So i am hoping that the way I have packed on the plastic to keep out the draft it will keep the chicks warm enough for the winter after I add lots of hay. I am adding play sand for sandboxs to my run for the chicks. The chicks at this time are between 9 weeks and 3-4months so I am hoping by the time it starts getting chilly in Ky the coop will keep the chicks warm! I will add pics as soon as it is done.
