Green seeds or parasite?

[Raynathecrazychickenlady]

So today I noticed what appeared to be tiny green seeds in my chickens poop. A lot of them. I donned gloves and checked throughout the poop. The “seeds” can be squished and an audible pop is heard and white paste comes out. But could this be parasite larvae?? They have access to grass and dirt, I feed them a mixed diet of different crumbles and natural lay feeds with sunflower seeds, flax seed… but nothing this small.. is it grass seed? I’m stumped

Not 100% sure, but it does look like grass seeds or something to me and it is that time of year. And I don't know of any parasite that shows up like that.
