We have had an unusual and EXTREMELY mild winter. All that is changing today. Single digits at night and teens during the day. My 8 month old hens are simply not adapted at all for the oncoming cold. I have two that have no feathers on their haunches. We have a very well protected light source in their coop. It is above their roosting bars. I'm thinking about adding an infrared reptile light...maybe 50 or 75 watts for the next two weeks (that is our projected cold snap). Has anyone used the smaller watt bulbs? I really don't want to add a 250 watt infrared as I think it would be too extreme the other way! I welcome your comments! Go!
