Hey Don, while I have you on here, I do have a general question for you. This could be something that relates to all fowl, but this is specifically related to large fowl columbian Wyandottes. I am wanting to work on the size, they have wonderful type, but would like to see if I can increase their size by about 10 to 15%....my only options really are just careful selection in offspring or outsourcing, yes?
