I found 3 of these (2 female and 1 male) in the The northern plains. If you are seeking them check there first but make sure you stack your bird withh extra meat. Also I recommend having Fur armor on so you do not lose food due to being cold.. also I bring vegetables with me when I look because it takes care of water and food really fast. These are hard to find so good luck!
If you wanna get wool without having to get ovis by just geting vegie cake make a cage with dino gate then get a argy to transport it into the cage then just simply shear it with scissors. Up if this is useful
