I purchased a cozy coop ambient wall mounted heater last year. I have three hens and one was ill for 9 months. She survived and has done wonderful. Their little coop had plenty ventilation and they stayed warm enough even for her but my problem was during the day. She wanted out with her sisters but it was to cold. We wrap our main run in the winter with corrugated clear plastic on north side and plastic shower curtains on rest and raise them as needed and leave ventilation at top . So I mounted (well my husband) our heater under the coop vertically in the run. She would sit by it during the day on the colder days. Did it help her really? Idk. But she did lay right up next to it so I like to think so. Just sharing what I use it for.
