My husband is in the military and we are being moved to Arizona late this spring. I have 4 hens-- 1 barred rock, 1 RIR, 1 black astralorp, and 1 salmon favorelle. I'm worried about keeping them there. Most of the houses we've seen have yards with no grass! We're in Texas now and it gets hot but we have grass! And a big yard that they free range in all day. Any advice would be so helpful!
