I had been using a 60 watt bulb in the coop on one end of it but I found a 25watt soft light bulb and put that in tonight.It seems mellower yet the chooks can get around and eat or drink etc yet sleep good too.Is that enough light for better winter laying?I have been getting alot of eggs about a dozen/d now.And I have one broody I let her sit on 6eggs to test my little roos out.All of mine are banties and most are cochins.
