I'm looking to get an automatic chicken door. For some reason my last post was deleted. Thought I'd try again.... First of all, do you let your doors operate in Winter? Or do chickens just stay in the coop? Secondly, if you do let your chickens out.....for people who get snow in the winter, which door do you use? I know the pullet shut gets high marks but a swinging door is not a good idea with some of the snow we've seen in NJ this winter. The ador1 is mounted outside which I'm thinking May not do too well with ice and snow. That leaves me doors that raise straight up and mount indoors. Thoughts and recommendations appreciated.
