I just thought I'd add that the Rangers seem to be developing at different rates. I've got some that are still quite small, whereas others aren't very far behind the cornish x's.
And while I'm posting, I'll also note that I've got orders for around 75 chickens, and I've only got 67 total. I want at least 15 for myself (probably all the rangers), which leaves perhaps 50 for everyone else. Obviously, I'm going to have to tell some new customers that they can't have as many as they would have liked, as I want to give preference to existing customers. It makes me wonder if I should build yet another pen for next year (that would be pen #3). With only 1 acre devoted to chickens, I'm afraid of getting too carried away, but 200 to 250 chickens per year probably isn't bad.
