Overall the Ameraucana breed is a docile one, but within the breed my experience has been that buffs are the most docile and silvers the least (or the flightiest). None are generally hard to handle, but my chickens are only caught and handled when needed. There are some folks that are more into exhibition and handle their birds often to make them even more docile for show.
The genes play a role and then environment does also when it comes to temperment.
I'm a little surprised to hear that the silvers tend to be flightier. I have mine in the brooder with wyandottes and a few Silkies and the silver ameraucanas are actually the friendliest of the bunch. They are always the first to greet me and fly up on my hands. When I try to take chick photos, they are always the ones jumping up in front of my camera to investigate while the others run and hide. They really crack me up. I'm loving their personalities.
Hello Amanda! Welcome to BYC
I live in berks county and have purchased layers from Pickering several times in the past. As much as I love the store, the Ams they sell are in fact, Easter eggers. Regardless, I loved all my hens from them! They were all fabulous layers and the egg color one them was gorgeous. If I can find any pics of them, I'll post them! In the meantime, if you're looking for true Ameraucanas, I can help you out connecting you with local breeders in the area.
