Sorry to hear about your troubles. I don't have a clue about what's wrong, but I agree with the Crohn's idea. (BTW, have any of you heard they are treating Crohn's, a bacterial infection called C. Diff., and other issues with a Poop pill? It is what it sounds like healthy poo from another healthy person, usually family member! Share the love! Haha). Totally went off topic...
Anyways Barbiegirl, be your son's health advocate and trust your instincts.

g I was quite sick early this year (had to stop working) and I had to switch Drs. to find one that would listen to me, because I knew what was wrong, but my previous Doctor would not listen (even though the treatment was harmless!).
Chicken question: Has anyone heard of the "Cottage Hill" line of Black Copper Marans? I have the opportunity to buy some in the spring. They are a bit more expensive, but I don't mind if they are a good strong line. Even if egg production isn't super high.
