One of the best butchers in the Quakertown Farmers market is Fredericks. The counter is packed on Saturdays and quality is the reason why.
Chicken breasts are always choice, as their prices on this per pound item is always competative. Also, check out their smoked meats, and especially their sausages. I recommend their breakfast sausages!
Get there on Friday evening, early, get a number and do the wait for some of the best meats in the area. Look for the sales flyer for their weekend specials.
