What is an extension office and is there one for every county in the state???
A county extension office is usually connected with the State University, and can provide guidance on weed control, best grasses and/or crops for that specific area, is usually also able to provide information about 4-H, probably weed control (although I'm not 100% certain on that), weather conditions and yearly rainfall if you're new to the area, plus a host of other things as well. Most counties have one, and you can find it by looking in your telephone book. If memory serves (I don't have a phone book handy to check), its listed in the white pages under government, and the county name.
Flushing typically means the removal of eggs from a female. Those eggs can be fertilized or non-fertilized, depending on their intended usage. Usually some type of fertility hormone is involved to cause the female to release multiple eggs prior to flushing, but not always.
As far as the best types of hay, that is going to depend on your goals, area, what is available, and what else you're feeding. As far as pure protein is concerned, I think you would have a hard time beating alfalfa - but, I could be wrong on that.
