Speaking of all of this has me thinking about banding everyone. I can tell most of my cornish cross apart by combs and personalities, but I couldn't rely on identification for something like med administration or anything more important than just knowing who's typically in the nest, who is friendlier or nippier with treats and who is picking on who. Anyways, my point in that ramble is, what bands are best for a large varied flock? Do you guys do like assorted sizes bags or buy bags for eachh and every size of bird that you have?
