Hi, we have 7 baby chicks that we got 10 days ago from a mail order hatchery. This afternoon my husband discovered a poo with what looks like a smooth round worm in it. The worm is about the diameter of a piece of cooked spaghetti and about 1/2" long. This seems really big for a little 10-12 day old chick. Everything I've read on this forum indicates that chicks that young don't usually get worms, especially not bad enough so that you see them. They have never been outside or exposed to any soil. We have them in a large cardboard box with pine shavings in the bottom. All the advice about using de-wormers seems to recommend waiting until they're 4 months old. What should I do? Thanks!
