I've been battling a respiratory issue for a few weeks now with my 2+ year old BLR Wyandotte. She started with weird looking breathing (her neck would expand and contract (not up and down, but out), then a couple of days later she flipped out, woody woodpeckered the wall of the coop when I locked them up for the night and spattered blood all over. The next morning If I listened extremely closely I could hear a faint muted clicking noise when she would breathe. That night when I locked them up she turned her head to look at me and she had a mouth full of mucus. I panicked, made a dosage of Denagard for her and forced her to drink a few sips before she spilled the whole thing. I put the entire flock on Denagard (dosage for treatment) the next day and she made what seemed to be a full recovery. They were dosed for 5 days. Took them off and within a few days she was back to the weird neck breathing. Put them back on Denagard (preventative dosage) for another 5 days, she got better, just took them off 2 days ago, and she having trouble again, although this time, not only is she doing the weird neck breathing, but she will push her neck down into her body and then lift it back up, and I'm wondering if she has mucus in her throat. At this point I don't know what to do. She's eating and drinking and walking around normal. She just can't seem to shake what she's got. I don't know anything about any other meds other than corid for cocci, and this Denagard which Dawg was so nice to suggest to me last year when I had a respiratory issue. Any suggestions???
