@jackiezim Go with the velcro - costs less & works better. I bought the collar & my roo took it off in 2 minutes. I kept putting it on him & he ended up getting faster taking it off. Took him 2 seconds the last time I tried it. Went to Joanns & bought 1/2 yd of 2" wide velcro & it works! I have it on him because he has the most annoying crow - sounds like a woman screaming while being strangled. My other roos have pleasant crows & they don't have collars on them.
