Yes, the swelling in the rectum may be a mild prolapse, and is generally
due to straining in animals with diarrhea.  The blood in the stool, if it
is fresh red blood may also be due to straining, or we may be dealing with
a case of colitis here.  After he defecates, rinse his anus with a small
amount of cold water, and apply a dab of a mixture of one-half preparation
H and one half 1.0% hydrocortisone cream to the area.
 
Animals generally only contract ECE once, so he may have a chronically
inflamed bowel.  In generally, animals with diarrhea tolerate kibble very
poorly, so it is probably not a good idea to allow him access to it (it
may have contributed to his yellow, runny stools.) No, the yellowness
isn't due to eggs (I am not a fan of raw eggs as part of a duck soup
mixture), but the fact that the stool is coming out undigested.
