IMHO. There's almost nothing more heartbreaking then the no crow collars.If it is a noise issue have you thought about a no-crow collar? It's heartbreaking when they have to get separated. If you want to add to your flock, your girls tend to go broody, if your up for waiting till next spring you could have mama chick. this is the easiest way to introduce more chicks
Anyone considering using one should do some real research on them and by research I don't mean just reading what the companies that sell them have on their websites.
