I have three female 4 month old ducklings with my chickens. My Cayuga has recently started coming up to me with a low quack and standing there as though in a trance while I pet her and then after some time, snapping out of it and moving away. While the ducks have always been friendly and will eat out of my hand, they never have allowed me to pet them before. Is this behavior equal to the chicken squatting behavior or something else? Thanks!
