I have four runner ducklings and I am in the midst of building them a house. It is 7.5' long and 3.5' wide and high. I've been going back and forth about the best way to create a floor for them. Does anybody have suggestions with regard to wire vs. plastic vs. wood vs. other floorings? My landlords (i.e. my parents) have not taken too well to the "deep bedding" concept that I've read so much about. Is there something that can be added to the mixture of feces and bedding that would reduce the likelihood of eye infections? Thanks!
