So I'm in TX and have a 3 sided coop and the 4th side is hardware cloth. My plan is to plexi glass part of the open side when it starts to cool off, I'm guess at least another month, but when should I start to worry about it? Tonight it is going to get "cold" at 43 degrees for the low and tomorrow will be a low of 45 degrees. The rest of next week will be in the mid 50's for the low. Maybe it will finally kill off the mosquitoes! At what temp do I really need to be concerned about keeping my guys warm? I added extra bedding for tonight and know that they will be fine I'm just trying to not get caught off guard.
