Hello! My hens will be on their own for a few days while I’m out of town and I have someone to check in daily, but she can’t be there in the morning and evening to open and close the coop door (it is always open throughout the year as our run is very secure, but I’ve been closing it at night in the winter.) If I am sure to wrap the whole run in plastic will that be ok if the nighttime temps are in the low 20s? All of my breeds are cold hardy. Thanks!
As long as you run is very secure otherwise the only things I would worried about is predators. I leave my pop doors in my coops open 24/7/365. I do have electric wires around my coops and pens, concrete under the gates and good heavy duty netting covering my pens. At least you do have someone to check on your birds. Good luck and have fun on your trip...
