Hello! Quick query: My five ex-batts are now very well adjusted and doing "hen" things. At night they trot into their coop & put themselves to bed. But with the summer dawn, they are awake at 4am tapping on the door to be let out. Sometimes one of us is up then, but more usually it'll be around 7am. Their coop opens directly onto a fox proof & covered run, part of which has a sun shade, and their run is where their feeder & drinker are (among other things). When should / can I leave the coop door open overnight? I figure that in cold weather, they need it shut to avoid draughts. But in summer, will that matter so much? Plus, they might want to get out in a hurry to rehydrate if it's warm. The coop is probably at maximum capacity (tho my hens seem to fit fine, and don't bully each other) whereas the run is spacious. I haven't noticed any problems from making them wait til we get up, but would like to pre-empt any possible issues. We've only had them for 2 months so it hasn't been warm before. Automatic opener is not an option as the pop hole slides sideways, not up, and there isn't any room between coop and run entrance. Advice welcome! Thanks!
