I think part of the problem is many of us here [probably the vast majority] are fairly inexperienced & reluctant to answer because of it. There are many aspects of chicken keeping I have little 1st hand knowledge of: roosters, hatching, chicks, brooders, American predators ~ none of these are my day to day experience with chickens. I do try with the things that are more general or I am fairly confident with but unfortunately I think real expertise always comes down to just a handful of people & the bulk of the burden falls on them.
