Hi all! Quick question about using Safeguard paste...I wormed my 4 hens 2 days ago with a “dollop” of safeguard paste. They are all acting fine but I had seen 1 hen pass 1 roundworm so I decided to worm them. They are just turning a yr old and healthy Orpingtons..laying good etc. I have not seen any worms in their droppings....should I worm them again in 10 days. Is 1 pea size dollop enough for these large hens?
