Some keep their birds on wire I have seen calls on it mainly, but I think it can harm their feet especially when so tiny. But you right it will sure help with water splashing. Maybe just coverall but where water and feed will sit. If you have nice warm days you'll be able to let those little ones out to enjoy the fresh warm air. It will help them acclimate quicker too also that shelving stuff that is like soft rubber that is easy to use and can be shook out and washed. I would like something like that to keep my hateful scovy's in when they go broody to break them. They are so mean to their flock mates at those times.
