I am super happy with this chicken coop and have added a chicken tunnel and large dog cage kennel to expand the enclosure foraging space. The tunnel and dog cage is not permanently attached and can be moved around the yard with the coop. I purchased a solar powered roll style automatic coop door that is predator proof with flashing lights and a silent horn. My chickens are safe in their coop and I don't need to open and close the coop door each morning and night. It's important to have a closed coop door at night because some weasel or fox can dig under the enclosure, but cannot get into the coop if the door is closed. This coop is exactly what I wanted and the price allowed me to be able to extend the enclosure!
