(They're beautiful! See if they'll let u get close. If so, try a net or just catching them with your hands, if not, try a live trap maybe? See if you can get some of your family to come over and help catch them. If you can't convince them to keep the hens, u can always rehome them. If you can get enough ppl u could corner the hens and catch them both by hand. I'm used to catching chickens that way. Get two or more people and chase them into the other persons arms or towards a structure they can't get through to corner them urself.
