Yikes. How horrific of a thing to have happen and witness. I'm sorry for your loss and traumatic experience..
I have three, 4 month old straight run Silkies myself. I got them as day olds.
Here in Hawaii it is illegal to have roosters within city limits (thank God). And of course I HAD to have the breed that can only be purchased as straight run chicks. LoL. AND cannot discern pullet from rooster until it either lays eggs or crows (and doesn't).
I thought one showed signs of roo-like behavior when they were younger but now I can't tell. They could all be cocks, hens or ninja turtles for all I know.
I love all 3 but am still hoping for all girls.
I have never heard of this "bark collar". I got excited when I saw such specificities to my potential problem. "Silkie, Roo, crowing solution." Only to further read your horror story.
I guess this is a unique situation where a product's potential to cause death is an acceptable risk? Being that it's used as a "possible" means of avoiding CERTAIN death? In the event it becomes necessary, it may still be worth a last-option shot. If the alternative is for him/them to become Panda Express anyways. :/
It still seems fishy to me though. If this were a dog collar, this incident would make national news I'm sure. Quickly followed by a non-disclosure settlement out of court and a quiet recall.
I read here that Silkies are of the quieter breeds. Even the roosters. Was that not the case with Miguel? (I'll go read your other posts to fill in the back story.)
We have wild hens here that squawk just as loud, early and obnoxiously as any rooster I've ever heard. Except these nice hens do it intentionally on my doorstep...
Maybe they'll be good for finger pointing fodder if any neighbors start complaining about my urban free-range flock (roo or not).
"Mine are pretty, well mannered, play with the kids, cute and fuzzy. It's THOSE hood rats that are the nuisance."
Again, sorry for your loss and this traumatic event. But thank you for sharing your experience with us. And letting your experience possibly help others.
