Hi - 8doubles - I take it that is a joke about your fishing prowess.

But who can say - it might be worth bringing some back and fermenting it out like comfrey leaves and offering it diluted in water.  The stuff I use is pretty expensive to buy, but it is dried and nice and easy.  It says on the bag Seaweed Meal, and from memory when I was researching it a few years ago I would guess that any seaweed will do. 
I use it on the garden beds, round the flowers, and give it to the animals and birds I keep.  Certainly the flowers have a more vibrant colour, and I think my veg eggs, and dare I say it chickens sheep pigs cattle etc all taste better.  It might be subjective but - I think -therefore it is.

All the best
Sue

Interesting about the sea weed  isn't it salty and isn't salt bad for the girls? just a thought.

I think most animals need a small amount of salt to stay healthy except perhaps slugs.
If the hens had the chance to peck a small amount once a fortnight it should not be detrimental to their health and may even be a good tonic.
Even the local sparrows scrape salt off the brick walls to supplement their diet.

I bought a tub of dried seaweed for chickens and mixed it in with their layers and they left it - they ate the pellets but left the seaweed in the feeder
