yeah my golden comets do that all the time to. We always called it shouldering (because it looks like they are putting up their shoulders.) I either just pet them or pick them up depending on if it's time to put them away. It does make them 1000 times easier to catch then when they are in their flighty mood and we do the chicken chase.
Hens and pullets do that. They start before they start laying eggs normally, and it's a way of saying, "you're dominant, I'll squat for you." Roosters stand on their shoulders for mating, but it's also a good way to pet your hens since their shoulders are spread apart.
I give them a shoulder massage, then grab their tail feathers & give them a good wagging. They won't leave me alone till I do. My partner calls me "Rooster Mama".
Heeeheee,
Can't wait to tell hubby that the girls think he's "da man"! Too funny! I have two one year old girls that do this often. Although, they have been laying well for more than six months
