I bought Wazine and Safeguard; for worming do I use the Wazine first 7.5 ml per quart of water , do this for 24 hours. Then in 10 days use the SafeGuard 2.25 ml per gallon of water for 3 days; repeat in 10 days. Is this correct? My pullets are only 6 weeks old and 1 week old, 2 of each age. Is it too early? One of my pullets had black runny poop so I'm thinking she has worms. Thanks for any info!
