yep, everything with a gizzard, needs grit or dirt or stones of some form, it is what grinds their food to aid in pre-digestion, basically it how they chew.

Hi,
I saw your entry about your ducks eating everything. I have a 3 mths old call duck and she's I think she's constipated. She's kept inside w/ me as she's orphaned. I have her on recycled paper small-animals type shavings & feed her Mazuri waterfowl maintenance feed. I think she ate some of the bedding. She's alert & drinking and eating a little feed, eager to eat greens. She only passed a little droppings yesterday when I had her out to play for about an hour. I.m cleaning her cage this am to better monitor it.
Any suggestions? I'm trying to make sure she's ok today. If there's no improvement I'll take her to bird vet tomorrow, but they're closed today. She.'s my baby so I have to get her thru this. Thx!
