My girls seem to be doing just fine... but the other night it got down to -1 and that was too stressful for me. So....I put in a heat lamp, but used a 100 watt bulb instead of a true heat lamp bulb. The girls had a couple little spots of purple on their combs, but didn't seem stressed by the weather. I however am feeling like they deserve to stay warm...lol Am I spoiling them? It can't be good for them to have their poo frozen in the morning! I know the forum ppl say they don't NEED heat, but jeepers... they need to stay warm, right? Any thoughts???
