It's over a hundred degrees here, and my Cornish Rock cross are 7 weeks old. We were planning on butchering this weekend. I'm not sure they will all make it, they are panting like crazy. 2 of the biggest sound a little wheezy even. i put out 4 extra gallon waterers so they wouldn't have to walk at all to get water & put electrolytes in there too. They can free range and the run has several nice big shade trees. not sure what else I can do. I'm going to try to talk DH into staying home in the morning and butchering the biggest birds.
