I was wondering if you could go into why Thranduil is acting the way he is on the recent rookery post with Herian, Pel, and Sina.

From what is being said publicly on the post this Dalish clan has attacked before and the negotiations were a trap. All three were tortured. This is a work of treachery and betrayal and while I'm no expert on Tolkien lore, I was under the impression that would come above other issues considering what all has gone on for the elves of Tolkien's world.
