Wish me luck. I'm finally nearly ready to give this a shot. I've got the tools ready. I've got two birds who are VERY hungry and thirstyAnd I've almost got my courage screwed up.
As luck would have it, my partner's not feeling well today, so I'm all on my own. I expect I'll lose both birds, which is partly why I chose two of our oldest cockerels. Because when I'm done there will be enough meat to go into a soup for tomorrow's dinner. They're nearly twelve weeks. They've had an excellent life. And someone's got to be the first....
Good luck to you! (And the birds!

You can do it. Slow and steady, then get them back to food and water and they won't even know they are missing a few parts.
