Cumberland Farms is a store on Hwy 48 just past Food Lion on the left (just across the McClure bridge heading towards Dickson from Clarksville). They sell plants, primitives, rabbits and poultry. The owner and his wife incubate all their own, and their primary goal is good quality dark brown egg production so they breed to bring out those traits, with the exception of the easter eggers of course. I am not sure about any certifications that they have as they have not had any of the breeds I am looking for, and I haven't had much opportunity to just talk to him because he has been very busy everytime I have been there. They do have a wide variety though, Welsummers, Brahmas, Cochins just to name a few. He does do special orders, and I have talked with him briefly about a special order for next spring. I am currently looking for marans and wyandottes, which he does not deal with any longer. I will get his phone number for you so that you can call and talk to him.
