Yesterday morning I found two round worms on the dropping boards. So I knew I had to worm again. I wormed early spring with Wazine and now it is hotter it seems I have to worm again. So after reading and reading and reading, I purchased Safeguard goat wormer at Tractor Supply. Here is the Amazon link: https://www.amazon.com/Durvet-Safeguard-Goat-Dewormer-125ml/dp/B000HHLVB8 I gave all 22 chickesn .5 ml by syringe, but this morning I did not find worms. I found that odd. I did find tape worm shavings similar to this image: https://homefarmer.co.uk/wp-content/uploads/2014/05/431332_534451319913210_1598108975_n-300x225.jpg What I'm unsure of is if I have to treat the chickens for 5 days straight or do I wait and reworm in 10 days? Also I find it odd I found no other worms when they were in the droppings the morning before.
