I am new to keeping chickens (and to this forum!), so thanks in advance for your help! I have a small flock of red sexton hens (4) with one rooster (supposedly a Sumatra, but looks more like a Maran). When I let them out of their coop yesterday, I discovered a fresh pile of poop with lots of roundworms.... not a fantastic way to start a Saturday, to say the least I've read in my "raising chickens for dummies" book that I need piperazine to get rid of these, but have no clue how much.... a google search directed me to a conversation in this forum which mentions other drugs. I have no idea what is best or safe for my chickens. They get organic feed, fresh water, and a small amount of scratch with a bit of oyster shell and flax seed daily. I contain their droppings from roosting into bins under the roost, and clean these out once or twice a week. They are only in the coop at night, and they are contained in a large run during the day. At first, they were allowed to free range while we were home, but an attack by an unleashed rottweiler from next door stopped that We put up the run soon after. In general, I'm feeling like a bad chicken mommy for now having chickens with worms Any advice is appreciated!
