Where did you get it? And how well does it work? My problem is that roosters crow all day long, and I can't keep them in a box 24/7 - that defeats the purpose of having a roo.We have a rooster box.
Roosters are not allowed at ALL within my city limits. Hens are, if you are zoned for farm animals. There are some exceptions to the zoning rule - for hens.
I have tried the no crow collars, but I can't seem to get the results that I see on all the videos. I was using it on a silkie, so I made a smaller width one - still they were much louder than the hens. And my hens can get pretty loud when they are fighting for a favorite nesting box....
