Are your birds laying yet? Wazine is what most use as a wormer for poultry. There is a egg withdrawal recommended of two weeks. I am originally from MI., Traverse City. Been in Florida most of my life. We moved to St Petersburg when I was young and now I'm retired. My brother moved back to MI about 1973 as he met a gal from Interlochen (spelling ?) and she wanted to be near her family. About 15 years ago my DH and I moved near Ocala (Dunnellon) and my sister now lives in Sarasota but is moving up to be near me. Her and her DH recently bought a place in Morriston. Good luck and have fun...
