What brand chicken to you buy? I only buy Kosher (better tasting). I usually buy whole chickens. Anything that is butchered, obviously, is going to be cheaper. But I’m not a butcher!
I use Japanese laminated steel knives and a sharpener designed for the blade angle and a steel.
Look up how to butcher the meat, easy. If you want to Kosher the meat, see above, I use a Kosher recipe on my Brisket excellent.
