I've decided to just make one. -making a platform that will be about 4 inches off ground, but no way to get under. Will a ramp be required of should they be able to do 4 inches? -the floor will be wood. Should I paint that? Should I get some kind of rubber mats/even yoga mats for easier cleaning or will they try to eat that? Should the inside walls be painted or left alone? -what is better--sloped or slanted roof? Which way would be easier for an access door? Should there be a slight over lap for roof or is that not necessary? I thought about a slanted hinge roof but that would be pointless because of the height and cleaning. -should access door be on one of the sides for clean up? I'm thinking 4ft by 4 ft for three ducks. Is that roomy enough? Thanks for any info.
