That's a good point about the day being too hot in many places. One that I hadn't even thought about, since we rarely go much above +20C here. I took the dogs out a bit before 8 today, and the chickens were still quiet in their coop. I'm going to go let them out soon, but I have to say it's nicer to be able to sleep in when possible, and the chickens don't seem to mind it either. Yesterday evening they settled in for the night around ten in the evening. Also, I'm aware of the fact that many people need to keep a second job in addition to their farming, and this requires pretty early mornings. I'm just trying to get the point through, that it isn't mandatory to get up at three in the morning to let the chickens up, if there aren't any other factors that force you to rise early.
The search for cheaper food has sadly led to overcrowding animals in confined spaces. People like to complain about it, and then when someone tries to do things a bit differently, they go out of business because keeping animals in more acceptable lodgings tends to hike up the price a bit, and none of the complainers buy their product. Dairy cows are lucky in that aspect, you need a happy cow to get 8 gallons out of her daily.
I have to say, while the chickens are pretty cute, it's not enough for me to let them into the house. I prefer to keep the couch free of fecal matter. Our landraces tend to come stand in front of the back door and stare in through the glass, and they've never even been inside the house. A bit of a hypocritical stance for me to take, since somehow the dogs have managed to weasel themselves into sleeping in the bed. How that happened, I know not. But they are the last ones to get up in the morning usually.
