I'm still trying to figure out a plan for our coop. I thought we were just going to get a pre-fab model, but now we are thinking about building. Have to decide soon since the chicks downstairs are growing lots everyday. I'm considering having an automatic door for the coop. I'm not yet sure if we are going to be running electricity to the coop. So I'm exploring solar options. Any opinions on which solar automatic door is the best for the money?
