I currently have RIRs, BRs and sex links. Have started another pen and would like to add some sort of special breed to our flock. The others will be our production-type eggs layers/possible meat birds. Any suggestions? I'd like a bird that isn't flighty or aggressive, not feather-footed and can handle the heat and humidity of south Alabama. They will be housed in a run that's about 20' X 40'. Thanks for your input!
