I'm going to be out of town for the weekend, and I can't find anyone to lock up the chickens at night and let them out in the morning...I really don't want to leave the coop open at night. They are in a fenced in area, but it is really not a predator proof run - no ceiling, just a four foot fence around the coop. I'm thinking of just leaving them locked up in the coop all weekend. I have 4 birds and the coop is a little over 4 feet by a little over 3 feet. Anyone have any thoughts? My other big concern is that it is going to be very hot this weekend...in the 90s and humid. The coop has a window, and good ventilation, and is under a shade tree, but it still might get really warm in there. Is my best option just to leave the coop door open and hope nothing attacks? Lock them up and risk the heat? Anyone want to overnight a Pullet Shut door to me?
