I am interested in rheas also, but do not have the fencing for them yet. So it is a hobby that will have to wait until I am set up for them. Found a ranch in Texas that is selling pairs, I think for $250, High Country Ranch.
I also am looking for lesser or Darwin rheas .. Got the run set up , but the seller I was waiting for had issues with there eggs , kinda glad I offered to pay more if they would incubate and hatch . As my incubator is well to small.
So I am indeed looking for 2 females and one male.. Or a few chicks and willing to travel far away from San Diego if the price is right.
