I have 5 breeder housing units and usually at least 3 more coops and runs. Runs range from 8X15 to 50X100. The toughest one is a hoop pen that's 8X50 and only about 3.5' high. However I do have 3 more pop doors in that coop I could open and make a small temporary run. The hoop pen is movable and it sits above raised garden beds. I rotate the beds so most of the year 2 of the beds are in seasonal vegetables, 1 is planted in a cover crop and 1 is chicken pasture.I don't know how big your run is, but I have a peice of wire that I keep attached to one side of the run about 10' from the coop so that I can open it up and stretch it across the run to close off the small section to keep the birds in a small area to be able to manage them and with the coop closed off we just corner one at a time then put them thru the wire into the large part of the run till they are all done. The two guys went out there to do my birds by themselves and my birds don't know them so they would have tried to keep away from them. Or you could keep them in the coop and catch them one at a time the same way. Idk maybe make some cages out of some cheap wire or go to some auctions to get some.You are right about not buying NPIP birds though. I really do not want to have to quarantine my pen for that is a sad state of affairs. lol The wind has nearly blown it over. haha ha
When I got those grown roosters that gave me heck trying to catch them I used some netting that my DH has in the shed it is a large net abt. 6'x6' and I had to throw it over the roosters to get my hands on them. They were wild I guess no one had handled them before. I handle all my birds from the day I bring them home so that I can manage them if I need to but also because they are so fun and I love them...
I guess I'll figure something out.
Thanks for the input.
