How to vaccinate a pigeon

[Lovebirds]

I just found this on YouTube by accident. This is the exact way we vaccinate our birds, except for a couple of things.
First of all, it takes TWO people for us to do it. I don't know how he holds the bird and sticks it by himself. I mean, obviously he does, but that's one calm pigeon is all I got to say.
Second of all, he states that he uses a 22 gauge needle. I can see the pigeon flinch two different times when he sticks it. I've never seen any of my birds flinch when we stick them with a 20 gauge needle, which is what I've always been told to use.
I guess a 22 is bigger than a 20 so the vaccine probably flows through a little easier, cause it is a bugger to push that stuff through. Maybe THAT'S why he can do it alone...........
Anyway.......I posted this mostly so that you can see how to give the shots in the leg, rather than the neck.

PS: ok, just watched it again with sound....... He also says "5 milliliters"...........he means .5 or 1/2 cc/ml..........I don't know what would happen if you gave the bird 5 mls.........
