You can buy fresh chicken at a local grocery or at small gourmet food shops around. To pick the freshest chicken, you must keep in mind that there are two labels to read. The first one is the sell by date at the front and the other is, the package date at the back. Check for a package that has at least seven days left to its expiry.
At your state fair you can buy them for around 10$. It depends on the breed. Roosters cost more. Why you wouldn't just buy chicken nuggets idk, but If you want to kill it and pluck the feathers thats fine.
