Here are just three of the dozens of hatchery OEGBs (from multiple hatcheries) I have owned. There is also a thread with hundreds more pics from others. The black bird is too stocky and fluffy and the tail is not like any OEGB I've seen. I can give an opinion on the lavender since i can't see its body.
@btguy Can you contact the store and see which hatchery they use?
