So it's not actually in the henhouse (pseudonym, not a real chicken coop), but on the other side of the parking lot, you'll find alot of chickens if you went inside (including the mini rubber chicken I hid in there). Unlike the henhouse, this cache is open everyday of the week, but if you want to see the chickens inside, they're closed Mon-Wed (at time of posting). You DO NOT need to go inside to find the cache.
