Can I suggest you look thru, or post your request on the Texas State thread. This way you will be in contact with peeps in your area. Yes, Texas is a big state, but there are many posting there from all points in Texas. There are the Nationwide Hatcheries that you can find what you want in Day old chicks. Usually the quantities are 25 minimum. (especially in cool weather shipping)

I come across Old English Bantams at my feed store in springtime. Maybe check some of those near you, and ask what they will be getting in. Some feed stores can actually order certain chicks specifically for you. This way you would not need to get the large quantity. When store gets their delivery, they can notify you to come for them.
WISHING YOU BEST,,,,,,,,,,,,,,,,,,,,,,,,,,, and
