well, i looked and looked yesterday but couldn't locate any of the yellow diarhea that i had seen before so i could take the sample to a vet, but i did find a fiberous pile on a next box that contained some of the same color to it. So i scrapped it up, put it in a jar with water to seperate and see what was in it. Lots and lots of seed hulls.....and a large black rubberband or "O" ring! Although the yellow seemed to be a solid, i didn't try smashing any or anything. by appearance of shape it looked like flat corn. Oh and no grit in it either! So maybe she was stopped up by the rubber, malnurished due to undigested feed. I don't get it how that turned her blue but....could it be the condition/illness she had has already run it's course?
I had a hard time locating the gal but once i did she is regaining normal color in her comb and just as active as before. by last evening only the comb part right above her nostrils was still discolored.
Could be a coincidence but.....now i have to go back to the drawing board because it appears the drop in egg production has nothing to do with the 'ill' hen.
thanks everyone for your rapid support.
