Could be an instant cure for broodiness?
My husband and I were discussing how these videos were made - surely a real hen wasn't used in some of the shots in the second one?
Tony uses a GoPro camera to get aerial shots from his Phantom helicopter and his RC planes. The main problem is vibration from the motors, and stabilising the shot, and as this video explains, eliminating this is the gold standard for video makers. You can get a set of gimbals to mount the camera on (currently featured on his Christmas list, at a price equivalent to about 15 POL brown hybrid pullets, price has recently come down...) which does the same job as a hen's neck. But if you watch the videos closely it does seem as if the hen is moving in some of them. How would her feet be restrained so she didn't just blow away or step off the perch? Also of course it would be very cruel to try.
We assumed a stuffed hen was used, but it's very cleverly done.
