I've looked into raising chickens. There is so much that goes into it. Between their coop and bedding, cleaning and feed, the upfront cost alone is cost prohibitive. On top of that, everything wants to eat chickens. So if you have any predators (foxes, wolves, even dogs), they'll go after your chickens.
The egg prices have me seriously reconsidering it though
I wonder if you could search based on their latest sha prior to the fork.
Then again anything that makes it easier to find makes it an easier target for Nintendo.
