My runner ducks are almost 3 weeks old, that being said they are such little slobs!!! I am struggling to keep their brooder clean (my basement shower with additional level for sleeping) I was thinking about putting them in this bunny hutch I have, What I would like to do is put a piece of wood on one half of it so they can have bedding and such and leave the other half (where their food and water would be) as just the metal grate so that the poop and wettness could fall into a tray below. Will the grate hurt their feet? They will only have to walk on it to get to the food and water the rest would have a regular floor with chips. Also can they have a swim now if I am careful and dry them off well? They are dirty and need a bath.
