Use your judgement- only you know best for your situation!They have been going out to the run for about the last week. I was opening the door and they were going out but not off the ramp. Then one day they discovered the bugs and all decided to leave the ramp and venture around the run. The run is covered and is 8x16. I was wondering about the heat lamp because I have been working midnights the last week and when I have been checking on them in the morning I noticed they are all sleeping under the poop board. The light cannot be raised anymore and was hoping it's not getting to hot in there for them. The light is now 6 foot off the ground.
