What do you mean? Identifying breeds isn't way too hard if you know a lot of general information about a lot of different breeds and know what traits to look for. Your pullet didn't look red enough to be a rhodebar, and couldn't be a legbar because of her lack of a crest. Since she's barred, that also ruled out welsummer as a possibility. Though the cockerel in your other video kinda gave it away, since bielefelder roosters are a lot lighter than rhodebars and other similar breeds
