It's been really nice out all day so I have my 3.5 week old ducklings outside. I would REALLY like for them to stay outside with them being so big and messy and I have a 100w bulb in the coop. The part where the bulb is is made from plywood, and it is a pretty small area, about 2' x 4'. There is about 6 inches of pine shavings on the floor. There is a small hole as the opening into the run. I have a thermometer in there and it reads 76 now. Do you think it will stay warm enough in there for them? It is supposed to get down to about 40 or so tonight. Oh, also there are 5 of them. Will it help having someone to cuddle up with? Thanks for any tips or advice. I will bring them in if I have to!
