Hatchery birds vs. breeder stock have a very different appearance. Most of your fowl do appear to come from a hatchery, their body type and coloration is lacking. However, don't worry, they will make great pets, and layers!I paid $20 per chick! Why is it you all think they are hatchery chicks? And what does that mean exactly?
For example, here is a photo of a Non-Hatchery Stock Silver Laced Wyandotte

If you purchased chicks that where day olds, then your birds where overpriced if they where hatchery stock. Hatchery stock pullets average $2.00 - $5.00 each.
Now, if you purchased sexed pullets from a private breeder with breeder/show quality fowl, then the price is understandable
