Here are a Polish hen and rooster that we culled and butchered. They must have been at least 20 weeks old. I think aging them in the fridge for 3 days makes a difference. They weren't plump like a meat bird but both were tasty. Neither one was tough, though they did have texture.
I prefer to remove feed from the pen the night before. I leave their water. We hang them by their feet and cut their neck without severing the spine. My understanding is that they almost instantly lose consciousness from blood loss but by not severing the spine the heart keeps beating longer which helps with thorough bleed out.
Whether you skin them or pluck dry or with scalding is a matter of preference. We scalded these. I'm interested in trying pithing and dry plucking next time. Good luck!
ETA: that's half of the hen on a platter, not a dinner plate. She was small but not like a cornish game hen, lol.
