I think shadygrovefarm has it exactly right; "livestock production facility" is not generic, descriptive language that describes a wide range possible farming operations. Instead, it is a legal term with a specific definition. For chickens, it refers to an operation with 5,000 or more chickens; that is, if you don't have 5,000 chickens or more, you do NOT meet the legal definition of "livestock production facility".
This was discussed at some length last summer, in a conversation on this thread between me any Your_neighbor. Back then I said that it looked to me as if the Thomason case in Ypsilanti was lost because the judge did not understand when he read the same words - livestock production facility - that he was looking at a term with a specific meaning. Your_neighbor, who was pretty vehemently anti-MRTFA, agreed with me, on that point alone! See my post, p. 44 #431, especially the 2nd paragraph, and then Your_neighbors reply, in post #438.
shadygrovefarm, best of luck with your case!
DReyRose, if you need help finding the document with the definition of "livestock production facility", let me know. I knew where it was written last summer, and expect I could find it again...
