AND........how often? I gave my two Pekin ducks some today and just wanted to check. They absolutely LOVED them. I would throw the peas in their round bowl of water and it was about the cutest thing watching them fish the peas out. ALSO................do I need to put some grit out? Will they just take what they need and when they need it? Need some advice in these areas. Thanks! Oh............they are really enjoying their duck house and so am I. It really is a dream to keep clean. I put them out in a little fenced area today so they could eat some grass and lazy around. I also put my bunny, Mr. Peeps, out with them. They didn't bother each other and it was so sweet.
