I live in town where Roos aren't allowed; however, I'm pretty sure one of my lavender Ameraucanas is a gentleman. I would really like to keep him (bc now I'm pretty sure my flock have all become carriers of a resp disease- no we wont hatch any eggs). I have seen some mixed reviews regarding no crow collars online. Does anyone have experience with them? Store bought or homemade- I actually plan to make my own if I go that route- experience with either is fine. Any and all comments welcome and wanted! TIA!!!
