I saw parents to a little boy on my bus route have a large dog kennel and attached a brooding light to the side of the big dog house they have for them. They have lots of ducklings and chicks which are fully feathered though and the light is half outside of the house and half inside. I don't know if the light will break or what if it should happen to rain. I don't know if you could do something like that or not. It will get colder here this weekend with snow flurries. I am 18 miles East of Columbus, Ohio. Good luck with your babies.
