See i really need help in this department, if rotation is in order what do i use? i have no penned birds so it is important i worm all the birds here at one time not separate, ,ivermec treatments are the only time i catch them unless they are injured and it is an easy thing here as they will walk right into any pen i put up allowing me easy access to them, last years hatch don't even try to run, i just bend down and secure them, apply the doses and push-em out the gate they don't even know what hit them and if it bothered them they got 6 months to get over it making it easy to catch them again.There are also Pyrantal Pamoate, but don't know what worms it would be good for, if any, and piperazine, but it only gets roundworms.
