Those are definitely golden laced Wyandottes! I would try to catch them as soon as possible though, because at any second, they could get scared by something and run away. I also agree with
@Cinnamon11 you should try to use a large net. If you don’t have one, then you can make one out of fishing net material (or any material they won’t suffocate in) and a long pole, you don’t want to try to get too close because they could be traumatized by other people trying to catch them up close (who knows what they’ve been through!) and run away.
