9 Red Star and 10 Plymouth Barred Rock arrived in April. Started laying in August and have been great pets. I had a great coop built (8 x 10). I am using the deep litter method and I let my chickens out every day for at least few hours. My two Irish Terriers seems to enjoy the chickens. The Red Star are the best egg layers, nearly one a day. Barred Rock eggs have been smaller and less often. My coup is insulated and I have installed an automatic door. I have a heated base for the water inside. I have a waterer inside and out, and feed as well. Chickens do not spend much time in the coup and likewise do not eat or drink much of the inside water or food. As winter comes do you think an 8 x 10 coop is big enough as I assume they will not go into the 10 x 16 run much with all the snow in Wisconsin. I did install a 36 inch ceramic heater but not sure I'm going to use it. Should I close the chicken door all winter? Your thoughts are appreciated. First post!!!!!
