In that case, Amber could be a starlight green egger too - on a closer look she does have some lacing. My red sexlinks (ISA Brown and golden comet) look very, very similar to some of my SGEs. The proof will be in the eggs. Post back if you can once they lay, now I'm curious what you have!
If you allow shoulder perching, make sure you wear wrap-around safety glasses. They can peck your eyes without warning, and folks have lost sight that way. Eyes are just ridiculously attractive, and they don't mean to be mean, but THEY MUST PECK!!! because they are chickens.
In that case, if they sourced them from Hoovers (like they do where I live), Amber could be your golden comet, and the others could be Starlight Green Eggers and/or possibly olive eggers. No Prairie Bluebell Eggers that I see.
All 3 are female. Amber (bird with white tail and red body) looks like a red sexlink. The other two look like some type of Welsummer cross. They could be colored eggers, especially the one with a possible pea comb or modified pea comb (brown bear). What hatchery did you get them from?
