Around here they come to the local farm auction and buy up just about every chicken for sale. The auctioneer who runs the sale at his farm lets them butcher all of them after everyone is gone. He evn provides them with boxes and bags for transporting them. Everyone around here loves it because no matter the age of the chicken it sells. An old ugly looking rooster sold for $10 last week and that is average price. The whole color thing has not been an issue. They also buy lambs and goats but never a pig. I'm only an hour drive from Dearborn Michigan and it is said to have the largest Muslim population in the US. These people are hard workers and pay with cash. Never saw a problem.
