Hi there, I'm looking for advice and reviews of automatic door opener/closers. I am not interested in DIY--I want something pre-fab I can just install. Can anyone comment on a prefab door they like? I've read a lot about the one from Foy's on this forum, but I don't want a battery operated one since we have electricity at the coop. Has anyone used the McMurray one? I like the light sensor feature of both of those models. Thanks for any feedback on your pre-fab auto doors!
