I have an Ameracauna that is broody and doesn't care that didn't get above freezing the last couple of days and we even take her out around 4pm and today the wind chill was 13°F. We have some eggs hatching this Thursday I thought about sticking some under her. I live around 1000ft elevation on a mountain and the wind has been horrible the last few years and we can always expect snow until May. If she's a good mother, can she protect the chicks below freezing for a month? The forecast this week is above average.
