Hello, I recently purchased 50 roosters of the dual purpose Buff Orpington's for meat on May 8th. I'm wondering if there are any recommendations on feed? I started them on medicated feed for 2 1/2 weeks and moved them to Flock Raiser by Purina a few days ago which is unmedicated. Do I have to worry about worms or coccidiosis? Thanks, Farmer 123
