WHat feed do you use for chickens other than CX's? We have some roosters of different breeds that are around 12 wks that we want to process. They have been on grower all this time. Should I switch to broiler feed to see if they will fatten up? We were going to process them at 18 wks. I also have another question. I have eaten homegrown CX's from a friend that raises them and also some of our own roosters (not CX). Where they have good flavor, they are kinda tough. I talked to another friend who processed his and he said the same thing. Any thoughts as to why they are tough?
