I just finished processing my first set of Cornish X. I love the idea of raising my own meat but they were SO gross. I have curious about dual purpose birds....there are always ads on craigslist for free roosters. The one I saw this morning is for 3 Barnevelder roos that are 4 months old. I have a separate pen/tractor I can keep them in...feed them high protein feed for another 2 months then send them to freezer camp. Does that sound right? Dual purpose typically take 6 months right? They would need the high protein but wouldn't be crazy eaters like the cornishX.
