If you think they are getting tight, definitely remove them. The snap-on ones come in 3 sizes, I don’t know if the spirals do. Zip ties can be any size. Whatever you use, you have to keep on eye on them.I was using the little spiral ones, but as they grow, I’ve had to remove two.
Most of my flock is completely different. BUT, I have two lavender orps that look exactly alike. I think one is more social to people, but I can’t be sure. They might be taking turns.
Also, I have two EEs that are starting to look very similar.
So, are these big enough or will they eventually outgrow these as well? I thought the spirals would stretch with them, but that has t been the case.
