Oh, you are welcome. I think it would be okay to flush a few cc//ml into the vent, just not pull anything back out with the syringe. For a broken egg inside the vent, this would probably help with using a weak vinegar solution. I have read of vets removing contents of a stuck egg with a syringe an needle--sounds too dangerous, though. Beatrice looks like some of my chicks that were EE or welsummer.Thanks, Eggcessive. I had read about others having some positive results with a syringe flush/enema in loosening backed up stools. I hope I did not hurt Beatrice further by doing what I did. I just felt that, given her condition, she was going to die and I had to at least try to help her. I will have to look in to that further for any future emergencies. Thanks for the links to the articles. I just made a new solution of Corid at a higher dose. Based on what I am reading I was not treating with a high enough dose if they, indeed, do have cocci. I hope they will all make it. Just looked around at poop in the coop and it all looks good. However, Beatrice was A-OK throughout yesterday and then this morning was deathly ill, succumbing within an hour of my finding her to whatever it was that killed her. I felt so helpless. She died in my hands.
