Thanks to all, again.
Anything is possible in terms of what it turns out to be. George's oil gland seems clean and fine. No sign of external parasites. He's sounding perkier and looking better after two days now in the garage, eating the Raiser, greens and peas and boiled egg, on his heating pad (placed safely under the flooring of the crate which is bedded with chips) My husband is rather jealous, since I woun't allow an electric blanket in our bedroom, but George has one ;p
After spending quality time with George and re-reading H's book on health and comparing symptoms there are atleast three possiblilties, the dreaded Coccidiosis (I think we keep a clean pen and yard, though), hardware disease, parasites or nutritional deficiencies. Not that any are desireable, but I'm hoping for the later. I do notice that his breathing is a bit labored. Possibly because of his depleated state? There is no discharge from the nose or eyes. We're keeping him quiet, and visiting often. He showed no signs of wanting to visit the flock, even though one of the girls is brought in regularly to deal with her bumble (getting much better, thank goodness).
-How much time would you think I should allow to see signs of improvement if it is nutritional deficiency?
-Then I'll move on to parasites.
-Is there any definative way of knowing if George has swallowed something he shouldn't have?
Again, everyone else seems fine, so far, fingers crossed.
It feels like me entire day is spent treating ducks these days. Thank goodness this is a long holiday weekend!
All of your comments are thoughtful and I'm grateful for them.
