Is this poop normal!?

[amandaa]

Hello everyone. I cannot seem to find a picture anywhere that looks similar to my chickens poop. I believe it’s only 1 chicken, but I can’t tell. They free range in the backyard, so they eat a lot of grass w scraps and an all flock feed. Nobody seems to be lethargic or odd behavior. I’ve checked them all for mites with nothing found. They got a deworm last week. This poop has continued for weeks.. maybe it’s normal? It’s not runny and I don’t see anything weird in it. It’s just so green!! Thoughts??
