thanks for the replies,
I do have short planks of wood in the top of the racks, slows the waste down a little bit, but as they pull it thru the mesh some drops to the floor.
They are individual pens because of bullying and I put the milking bench across the front of 2 pens, so the rack can't come out at the front, the box idea would replace current hay racks, obviously a bit deeper, so I shouldn't lose much room in the pen, I've just been reading that they need to stand up on something or they still just pull their head back out to eat.
I would be worried about putting hayracks higher because i was warned they would get hay seed in their eyes, I did have problems with a youngster once, her eye looked quite sore but we managed to get it out.
I do use the dry top stuff and throw it onto their beds at the back of the pens.
I was buying horse hay last spring (Desperate) £6+ a bale and they managed to waste even more!
OK Jinglejoys I give up - whats B.P.G's

? Before ? Goats?
I have some old PSS and the Goatkeepers mag (before Smallholder), but still packed away in boxes following flood (roll on getting my built in bookcase).
googled 'Goat Keepers Guide' (Jill Salmon?) and bethought myself to google - 'keyhole hayrack', clicked on images and found quite a bit of information, american site homesteadingtoday.com had some interesting tips
Some look to have a shelf idea below the rack which the hay falls onto for a secondary chance of eating, but surely the goats would just stand on that and trample it there?
While cost does come into it, I'm more concerned about running out of hay and struggling to find any in spring again :-(, I'm going thru 4 bales a week and I'd say about half a bale or more is going on the floor,
