I have 4 four week old ducklings. I am really hoping to move them outside as soon as possible and they are in the coop (totally and utterly predator proof with a run attached)(but the door to the run is locked)as of now. I pit tons of blankets in it and hung up a flashlight and everything so they could see and everything is all set. It is almost night (7:50) and I'm having second thoughts because even though it is 61 degrees right now it might be 47 later tonight and there is a chance of rain. I can't give them a heat lamp becaue I can't get a wire to run all the way out to the coop (their coop is weather proofed too) Will they be ok?
