I discovered what look like inch-long thin worms where we're keeping our chicks, which are less than a week old. They're brown and immobile and I suspect one or more of them is pooping them but I'm at a loss for what do to. A friend loaned us some Wazine but I've seen mixed feedback on chicken forums — are they too young to tolerate it? Do they even need to be de-wormed? Thanks for any feedback. This is our fourth round with chicks and this has never happened before.
