Welcome to BYC! Glad you decided to join our flock. My wife and I were both raised in northeast Texas, but we haven't lived there in so long now, that I don't really know who has chickens there anymore. Please feel free to ask any questions you may have. We are here to help in any way we can. Are you wanted to add more Leghorns or are you looking at other breeds as well? Be sure to get all pullets, no cockerels, as you already have a rooster and the recommended ratio is 1 rooster for every 10 hens as roosters can be very hard on hens physically; over-breeding them, injuring them with their beaks and spurs, and battering them. I currently have 25 hens, no roosters, and I get loads of eggs without feeding any non-egg laying mouths, without the aggression, fights, crowing in the middle of the night, injuries, and over-bred and battered hens that frequently goes along with having roosters (especially too many). Good luck in getting some more pullets.
