I flipped a board over by our garden and found about 100 wood lice (sowbugs, isopods, pillbugs, rolly pollys, pick your term), so I dumped them in a plastic container and gave them to our ten day old ducklings. It took them about fifteen minutes to figure things out. First, they just watched them, then they pecked at them without picking them up, then they picked them up and spit them out. Finally, one enterprising duckling chewed one up and ran for the water and the feeding frenzy began. The container was empty in just a couple minutes. I guess I'll have to see about finding some more tomorrow. I know too much protein can become a problem. How careful should I be?
