Suspending water and feeder

I was wondering whether to suspend the water to keep dirt from being kicked into it  which lead on to thinking about doing the same with their feeder too.  My question is how high do you dangle them off the ground?  I've seen pictures where they are just about and inch or two off the floor, also seen pics where they are much much higher, what would you recommend.

I stand my drinkers on breeze blocks which helps keep the dirt out (unless of course they have had their beaks in the mud  )

Some of mine are on blocks, so about 4 inches off the ground.  My new red and white plastic ones have their own feet so they are 3 inches off the ground, but I read once ages ago that as high as chest height, which is what the ones in the hen houses are, so not only does it keep dirt out, but also stops them trying to get their feet in.

The plastic drinkers have their own feet too, but I don't hang any water up and it gets knocked around when they flap and fly around too much!

Mine are suppended about 5" above ground. The hens seem ok with this. 

I have my water feeders on filled, upturned plant pots so they can't tip or get dirty. I still find with hanging pellets feeders you do get some on the ground - chooks can be very messy!

Suspend the feeder at back height (above their vents) to prevent fouling but stand the drinker on blocks or bricks or a paving slab to prevent dirt getting in.  If you suspend it will spill bit by bit as they knock against it and will be empty in no time.

Your feeder should be under cover to protect from rain so suspend from the roof of a covered run.

thanks folks, will try suspending them and see how we get on.  Also thought it would keep them off the floor for more space to peck under too.  One of my chickens seems to prefer foraging than just standing and eating pellets so maybe if a few a split she will clear up and that way i get more layers into her too
