OK, here's the situation! We have 3 bantams in our playhouse coop (see below). The babies (now 18 weeks!) are in the coop/house most of the day and then free range in our backyard for a couple of hours at night. We then put them in the coop (or they go in themselves) at almost sunset, and we go out at about 9:00pm and close the hen house door. I then go out in the morning to open up the hen house.... usually at like 8 or 9, but sometimes I forget until like 10:00! This would not be an issue, however the FOOD and WATER are in the RUN-- NOT THE HOUSE!! So I try to get out and let them out as soon as I can. (I cannot fit the food and water in the run, it would be impossible to change the food water the way the house opens-- so this is NOT NOT NOT an option!!) To be honest, it would be MUCH easier for us to leave the hen house door open 24/7, so they can go out in the morning as early as they want, and they also have access to food/water all the time. However, I am nervous about predators! The coop is well made, it is on a cement pad, and has 1" welded wire on all sides, including the bottom. The door has a latch with a carabiner on it, and a industrial magnet at the bottom to keep the bottom corner closed. The egg door also has a latch with a carabiner on it. I have always felt that they were safer inside, and that they would be warmer as well ---although 1)the house does not have additional insulation, 2)we are in So. Cal and so the lows at night are in the 50's, and 3)they are Cochins, and heavily feathered, so I don't even know that they NEED the extra warmth. Are they safe enough in the welded wire compound that I don't need to close the hen house door?? Or am I asking for trouble???? HELP!
