@brksmith I totally get the "language" barrier! As far as the older reading material available on the internet it's been like trying to work on a puzzle that someone threw the box away for. Most of the tidbits I've found have been minor references on blogs or a snippet in an out of date book. Sometimes a name will get referenced that will lead to another rabbit hole that usually ends in frustration at not being able to find more information. I'm about to make a trip up to the "big city" just to get access to a larger library with a reference section. As great as the internet is there is little demand on creating e-books for such specific material. You'll find lots of great info on here to help with selecting a breed and such. Plus plenty of nice folks to chat chickens with. Thank you for bringing up an interesting topic! I'll have to dig through my bookmarks and try to find some of the older reference material I was able to find.
