Our sweet little puffball silkie rooster "Fern" (we thought she was a hen) has recently become aggressive. Admittedly he's a silkie and not very intimidating but still…it's not fun for the kids (or adults) to go tend to our animals and be pummeled by a rooster each time we walk into the barn. He flaps his wings, lifts himself off the ground and launches at your legs. If you give him the boot he just comes at you again and again. He is a year old. It's our first spring with him. Is this a spring thing and will it stop or is this something we'll have to deal with on an ongoing basis? We've tried calming him down with treats but he's more interested in "protecting" his flock.
