Thank you, Kassaundra, for that link to the BYC caponize post. Through the next few years I'll be keeping quail & may look into that for an alternative way to keep roos other than just processing (esp if one boy turns into a family pet). Later down the road I'll be keeping chickens & will definitely be referring back to that post.
I think, for practice it might be good if I try it on a recently culled bird, strapped down but just pretending they're sedated. It would let me work with a fresh body & not worry if I make any slip-ups. Kinda reminds me of nurses who practice drawing blood with needles on store-bought, dressed chicken carcasses.; human-like veins without the worry of causing bruising or screams. XD
