I ended up adding 2 Brahmas , a light and a dark.
Egg production wasn’t a major need. I still might add some Jerseys in the future.
I'm interested in Brahma's also. I've been told that they're calm, docile, friendly, and not as likely to spook or fly over a fence as other breeds. I'm somewhat concerned about the summers. We probably have a similar climate here in Southeast TN. Let us know how it goes.
