We are in South central Texas, very hot already, upper 90's, been 100 twice this week, stays in the mid-70's at night. I have 19 3-week old Brahma chicks in a large brooder in my living room but would really like to get them outside into their safe, well ventilated coop. They will be in full shade all the time, but is the heat too much at this age? I keep thinking- better to get them used to it now, before we get even hotter!?!? Thanks!
