most dont expand. especially from chick to chook.Thank you thank you thank you!!!! Now I gotta find 'em online and buy some. They expand, right? So I don't have to worry about cutting off circulation?
I use zip ties and make them lose
one at hatch
i change it when I put them in the grow out pen
i change it at 15 weeks when i give routine pre-laying mite and worm Ivermectin
setting dates to change leg bands is a good reason to pick up my birds and inspect them
