Kelp ( not powder)

[Larryirl]

How much kelp can i give per kg of bird in a serving . I get dried organic here in ireland. Then soak it. Wash it under tap a little then cut into small 3mm by 3mm size peaces and stir into wet pellets 2 mornings a week. Its messy but they love it and its easy to add stuff to it. B& G macaw and a senegal. Rainbow lorikeet gets a little also. Struggling to find information on not powders kelp servings. The cokoured chickens eat well and now so does the bird daddy.
Cousins 3 year old was here a few days ago. My mam : whats that upstairs
Child: a big chicken ...... in a trap

I'm not sure to be honest! I know too much can cause hypothyroidism or hyperthyroidism so I'd be concerned about overdoing it myself!

Kelp contains a lot of salt

When my large birds were iodine deficient, our avian specialist had them on 2.5 ml of rehydrated kelp mixed with their chop, once a week. And that was for birds that were deficient per blood lab draws.
I do not think I would give even close to that dose to a healthy bird not deficient.
