for when they are feathered out to not need the heat lamp, but still too little to be added to my older hens. And I figured I might be able to use it for broody's too. Here it is. I paid $350 for it, and it's practically brand new. I just have to replace the chicken wire with hardware cloth. http://sacramento.craigslist.org/grd/1473281488.html So do you think with the older ones seeing them through the run, but they sleep in different areas would be enough of a transition to slip them in my main coop at night?
