Ok...I have 14 hens that need worming (round worm). the directions on the Wazine bottle are 2 ounces per 2 gallons water for 100 birds. So I figure I need about 1/8th of an ounce of Wazine for 2 cups of water, is this right???? and if it is how in the heck do I measure 1/8th of an ounce -and yep I know Wazine is not approved for egg layers but what am I supposed to do?? will destroy/not eat the eggs for at least 3 weeks.
