We got snow...down south got more of a mixture. We were suppose to go to Springfield tomorrow, but not with the ice coming. We are going to be hit and miss until tue. I have the small door in the coop open, if they want to get out, but they usually stay in when there is snow on the ground.
We use one of those dog bowl that you can plug in, for their water. It works pretty good. I have my Polish in the garage. They drink from a fountain. Their feathers get in a bowl and cause their face to freeze, so they are spoiled right now in the garage where it is 60. We are going to build a big coop this spring.
As far as the light bulb, we had it in an upright postion and now we have a heat light in it facing down ward. If they were to try and perch on the bulb, they would slide off. We moved the perches so that they can't get to the light, but don't say they won't. I added a BUNCH of bedding on the floor.
