Hi everyone! Quick question! My mom has been getting very worried lately about our chickens as we are quickly approaching freezing temperatures. I have been telling her that chickens can withstand very cold temperatures without supplemental heating, but she still is apprehensive. Our coop is on the small side for 6 chickens (we are debating whether to build it larger) but it is working for now. We always have one big freeze every winter where it can drop down to 15-25 degrees Fahrenheit. But during the winter, nights (and occasionally days) are always at or below freezing. My mom has suggested using a convection space heater and placing it outside the coop to warm the air. I have warned her about the dangers of coop fires, but she says that this is safer than a free-hanging bulb. What are your thoughts on heating? And what should we use? Any help appreciated! Thank you!
