About 4 months ago I was brought an abandoned wood duck egg and he ended up hatching out a week later on Easter Day. I was totally clueless, but since I breed bearded dragons I had plenty of chick starter for feeding my live bugs. It didn't take long to figure out the chick starter wasn't going to work, but he started eating small super worms the next day. I also had the Mazuri Insectivore feed on hand so figured I'd give it a try after reading wood ducks ate a lot of invertebrates in the wild, and the local feed store didn't stock the Mazuri Waterfowl Starter. Needless to say, he loved the Insectivore and still eats it quite a bit now, but he favors the dubia roaches we farm for our reptiles and will go over to the bins to beg when he wants them. I don't think I could have raised him successfully without the live bugs in the beginning, especially being an only child here. Just thought others would like to know about the Mazuri Insectivore in case of an emergency, it is fairly high protein (25%) so you wouldn't want to feed it to just any kind of duck.
