Hi I am new here. I moved on to my homestead about 3 month ago and as a house warming present a friend bought me 11 chickens 1 rooster and 10 hens (babies) They have been done by great but yesterday I found my rooster dead nothing to say why ( they have a preditor safe space) the only thing I believe could of killed him is the heat, I live in Texas it was 107 yesterday , they have shade and access to water but I’m wondering if there is anything else I can do to help keep them cool . I really don’t want to loose anymore
