Speckled sussexes with allergies?

Upate - I have my sussexes in isolation now, but they are doing better. I cannot find anyone around here that carries Denagard, may order it was a precaution. All the sussexes are doing better now, have them on electrolytes and have dusted them with sevin because I noticed that the very tips of their feathers looked ragged, but saw no sign of mites though I noticed at least one seemed to be grooming himself a little more than normal. They are eating and drinking, and I only saw one little sneeze yesterday. One of them still seems a little lethargic and likes to sit with his eyes closed, but he has always been like that. Wondering if I should worm them? The even escaped the quarantine pen and took off free ranging yesterday, but it was a different part of the yard from the rest of the flock.

Update - Although I lost one of my little girls to a predator, the two who were not sick are still not sick, and none of the other birds in the flock show any signs of illness. I am leaning more towards thinking that they inhaled the lime and DE my son was putting in their pen, he said again that it was all over them, he just didn't think about it hurting them. The sick ones eat and drink fine, and don't really seem as sick as they were, but one is still a bit lethargic and the other sneezes and does seem to breath a little hard after exertion. From what I have read, the damage from breathing DE can be permanent, but I hate to cull them, when they don't seem to really be in any discomfort and still look pretty good. Any ideas?
