I have a fishing net to catch my poultry when they don't want to be caught.
Since you are thinking of catching wild ones I would find their favorite hang out and then give lots of treats and grab with net and have a dog crate to house them for transport
Best of luck. I know my birds when they don't want to get caught they are tricky!
