I have a 2013 spring Hen who has decided to go broody. She is sitting on 5 FERTILE eggs. Shes a very small bantaM game hen and Im wondering how she and the eggs will do in the cold weather,with her only eating and drinking enough to survive because she doesnt wanna leave her nest,. I have place food and water dishes very close to her box but im worried bout the eggs. Should I put a heat lamp in the coop??? PLease any advice is very appreciated. PS:Spring I started my little chicken hobby farm,with only the essential knowledge of raiseing chickens.She is my only hen that has gone broody.So any extra info is also very welcome. Thanks!
