I made my own version of the No Crow Collar last night. Due to my novice sewing skills it's stiffer than I had hoped (thread tension issues with thinner fabric + Velcro). Anyway, this morning I got our little guy up early and dressed him in his new collar. I'd read about the walking backwards and trying to take it off, so I wasn't surprised. He can breathe fine and has been finding treats in the compost pile with the ladies, but he keeps trying to take it off and, more than that, the lowest chickens in the pecking order have decided this is an excellent opportunity to improve their status. He doesn't seem too concerned with their challenges and, what concerns me, I've seen him back down a few times. Should I be concerned or will it all work out? For those that use them, what were your observations when you first put the collar on?
