If you have back yard farmers/gardeners in your area You should be able to sell them, espsecially if the feed stores aren't. what they will bring is up to you to find out. I think all of the breeds you have mentioned will sell very well but the Royal Palms probably best, for the same reason you...
Our area is kind of saturated with RP's. There's been a guy on CL for 2 weeks now trying to sell some really nice looking 1 year olds for 25.00 @ so really like someone said before it all depends, do your research.
