I've been feeding & watering my birds (chickens, ducks & geese) in their coops where I can keep the heated water buckets plugged in & food dry for 8 months - since hatching. The birds are accustomed to going in at sunset for food. Now that it's not subzero at night, I want the little slobs to eat & drink outside. If I move the food outside, will they still go in at night? Is the security of the coop enough to lure them in? TIA
