I finished building my chicken run this past weekend, the space is 20'x20' with several shade trees and is completely fenced, including overhead. I live alone and figured that three chickens would be a good start just for me, I'm just not sure what breeds to go with. Although the run is shaded it gets hot as heck here in Central Texas. I was thiinking Australorp, Rhode Island Red, and Barred Rock. Would those be good choices? Any other recommendations? Ideal Poultry is about an hour away from me, they seem to have a good selection and I can get away with ordering under their minimum if I pick them up in person. Thanks in advance for the help!
