Greetings everyone, I am new to this site, but have been reading a lot of the articles. I have a question regarding my 12 Wyandotte hens. I bought them as day-olds and they are now 10 months old. I live in Northern Indiana and it has been very cold lately. We built a 4 foot wide by 6 foot long by 4 feet tall coop for the ladies and also built a 8 foot wide by 16 foot long by 6 foot tall run for them. We have the run and their dust bath area (which is under the coop) wrapped in reinforced clear PVC plastic tarps. My question is, can I put their heat lamp that I used when I first got them as day-olds in their run (not the coop) to give them a little more warmth during the day? I have wood chips on the floor of the run to help keep it cleaner (no muddy feet) and to help protect their feet from the cold ground. I am not putting heat in the coop because I am doing a deep litter system using pine shavings and do not want their to get burned or have a fire start. Any help would be great!
