i've lived in houston since '87 and i don't ever recall it going down lower than the upper 20's and that's in the north side. i live on the south side and i can't remember ever getting in the 20's, even upper 20's. i would be more worried about the summer heat and humidity here. make sure there are lots of ventilation so if they have to go in the coop to lay, you don't want it to be hot in there.
