This morning I happened to see my hen poop thankfully, because I saw a few small, white worms wiggleing deeper into the poop. It’s about 20 degrees here so probably to escape the cold. I dug through it but I couldn’t find them when they weren’t moving. She’s been acting fine and I haven’t seen any changes in her behavior yet. How do I treat this? Should I assume the rest have it? It’s really hard to spot, I was just lucky! Any advice is greatly appreciated!!
