So I would ask, how significant is the difference between sea grass and sea weed? The article below endorses sea weed for chickens touting its nutritional benefits. I'm not sure why seagrass would be different.
I don't know, Bob. I'm not a scientist. I can tell you the dugong [manatee] feed on sea grass, not seaweed, & that I have to soak & rinse the stuff if I want to use it on the garden beds because of the salt. Other than that I'm clueless ~ which is why I'm asking? There's some very scientific sorts on here.
If what you are worried about is salt content I can't imagine that the grass holds more than the seaweed. It's still a form of grass, however it is not porous like normal grass. That also would lead me to think no worries. It can't be full of salt.
I actually don't like to give cut grass to my flock because they can't easily control the length they eat as they can when plucking it off the rooted plant.
I think it would make great compost. Have you thought about piling it up and every so often letting them have at it. Not to eat the grass but to eat what is living in the pile of grass?
