This is a pretty good explanation of how I catch peafowl and why I don't use a net:

Basically, before when I tried using a net I would use a fish landing net like what you might find at
Walmart in the fishing section. I didn't like using a net though. I found it too cumbersome and I couldn't maneuver fast enough. I am used to going to the beach and netting little minnows, but something about swinging a big net at a bird just makes me feel worried that I will hurt them.
What I prefer to do is wear long sleeves and long pants, otherwise you will get a few peafowl scars like what I have. You may even want gloves, but I don't wear gloves. Then I use a small dog pen that is attached to my aviary as a catch pen. I usually need one other person to help me coral the bird I need into the small dog pen, then we close the door to that pen and I walk around waiting for a good opportunity to catch the bird. I like to corner them and wait for when their back is to me and I will grab them. I have seen some images of people carrying peafowl by the base of their wings. I myself think that might be kind of dangerous to do. I don't want to hurt the bird's wings. So I wrap my arms around their whole body, keeping their wings down. Then I bring the bird in close to my body to keep it from wiggling. Sometimes I have to re-catch the bird because they wiggle out of my grasp. Then, if I need to give them meds, I hold the bird close and have a second person give them medication and we use the method on the Hopkin's Livestock site for getting the birds mouth open:

Sometimes when catching a peacock, if he has a decent sized train I grab his train and use that to help steer him the way I want him to go and help in catching him. I don't pull on his train I try to hold on gently. It works pretty well.
I know some people catch their peafowl by the legs. I have never tried that and once I read a story about someone who tried doing that and broke their peacock's leg and he had to be put down. You have to grab both legs at once, or the bird could twist and break a leg. So I just grab their body not the legs, wings, etc. I try to give the bird some space and move in on them at the right time to avoid spooking them soo much that they ram into the fence. I think if you catch them by the legs you have to grab them above the knee joint on them as well.
Anyways, I don't catch mine to worm them but I have had to catch ones to sell, catch them to treat them for mites, and catch them if they are sick. I don't have any photos of catching them since mainly we are so focused on catching them and being careful with them that I don't think to get any photos.
