4 month cockerel- meat quality?

[Ridgerunner]

I'm processing a batch of 5mo boys mid-month for the holiday table. Here's the recipe I plan on using: https://www.farmdrop.com/blog/cockerel-alternative-christmas-turkey/

Sounds delicious. To convert C to F, brown it at 400 F then cook it at 275 F. I'd use a meat thermometer in the thigh to make sure it is cooked.
