I hear ye both, the balance In Width needs to be enough that they would comfortably exit. All criticism welcome as it hasn’t been built yet. And before anybody asks I think the cow exit area is too tight before hitting single file so that will need to be changed for sure. Idea is to use the space as smart as possible and we really could do with heifer cubicles so we are thinking of putting a single line of 20/25 cubicles and scraper between exit race and parlour wall (cubicles to go against the wall) and Will need to leave room for handling facilities at the top by parlour exit. Main issue is that an autodrafter would then be a part of the crush/race and it will need be far enough down the crush/race that they would be drafting into cubicles instead of the handling area above it.
2nd picture is potentially where cubicles would go (in red) but I would reduce this to allow for more handling facilities ie would go from 30 cubicles to 25 or even 20. Otherwise it’s really are not making life easier with cow handling.
