I have a friend with a similar setup Lord Flynn.
Birds are free ranging around the farm through the day and shut in their house at night.
the house has an 8'x4' wire run attached and the birds have access to it 24 hours with food and water in it.
its handy if the birds ever need to be kept from wandering for any reason but doubles up as a night feed and water supply which doesn't spoil the litter in the shed.
Bionic, I don't know what size of shed or number of birds you have, but would a small slatted or mesh area be a possibility for you so you could catch spilled water or feed and remove it?
This type of idea?
