My attempt to get my broody hen to adopt some guinea keets failed, so into the brooder with a heat lamp they went. Then I happened across the wonderful thread about using a heating pad to make an artificial broody hen and thought why not try it? I already had all the materials, so nothing to lose. And WOW - they love it! I went in to check on them after dark and was amazed to hear SILENCE! They were not making a sound and sleeping better than they ever did under the lamp. I only wish I'd found out about it sooner for my batch of chicks that just moved out to the coop. I will never use a heat lamp again!
