My COVID 19 induced rush back into chicken keeping has seen me purchase a wooden coop online that had no internal photographs. The perching is lower than the nest boxes, and we are now 3 weeks into moving them on to perches manually each night. I’ve decided to replace it with a Green Frog chicken medium loft. I wanted to add an auto opener with a light sensor but I would like to power it from a solar panel. Any recommendations as to what would be suitable?
