We raised them here in Tucson and like K9Dave said having raised hutches and shade is imperative. Also you can freeze water bottles to put in their cages. We kept ours in a rabbit tree (a building) with a fan and misters as rabbits can get heat stroke fast. Other than that they are very easy to raise.
For everybody using misters, I have a big question here... when do you turn them on/off during the day and how? On a timer? Most irrigation timer on market only gives me 2 hours of misting, is that enough?
Just turned on the misters the other day to try out.. Forgot them so it was wet in part of the run.. We usually turn then on for about 2-4 hours in the hottest parrt of the day..
