I don't have any problems but I know I need to worm my peafowl asap before they begin laying.. I have heard about a million different ways to do it. I have heard that worming in water may or may not be effective bc you don't know how much they are getting. I only have about 20 so I would prefer to catch and worm each one. Does anyone know what brand to use? I would prefer to give them a shot as I am a little nervous about opening beaks and getting it past the ________? I forgot the name. Any suggestions would be greatly appreciated! We have cattle so ivomec is available in abundance..
