I'm contemplating getting Jumbo Guinea Fowl and have been figuring out coop ideas. I'm planning on getting the 8' ×8' metal cage from Tractor supply and building an elevated coop inside for them to sleep in. I was thinking maybe I should put the access door for the cage up high, so they would have to fly up to the port maybe land on a shelf outside and then hop on in. Help with predators? Versus putting the access hole on the ground?. Also plan on outfitting with an automatic door so I can make sure they are locked up at night. What are your thoughts on the access port up high?
