The problem with zip ties is you're already at a point where you're gonna have a really hard time getting a scissor or sidecutter in there to cut it off, and that thing is gonna be good and tight within a week. They're alright on a bigger bird since you can leave them much looser, although I still prefer actual legbands as I've had zip ties tighten inexplicably on their own.
I am so happy for your chicks are doing great!! Do you have pics? I need a positive boost

. I want to have strong, healthy outdoor chickens
I am hoping that from now on I can raise my own chicks with broody hens.
