im from florida and heat is an issue for me. my ee's do well in heat.. i hand raise them from my own hatching and are sweet tempered and lay a large egg. i like australorps temperment but the black color ifs a negative for me. but my games do the best of all in the heat. my american games are the hardiest breed of any breed i have ever raised. Cali whites give the benefits of leghorns without the drawbacks as they are very curious and freindly birds. my wyandotttes due well in heat are quiet but not as sociable. i steer away from birds that lay more than 5 eggs a week because they tend to burn out to quick for my taste.
