Yet another issue has appeared for my poor chicken. There was another egg today, so I started checking vents to see who else had started laying. Thats when i saw her vent, could this be from laying an egg for the first time? She was very sick about 10 days ago, she may have had bronchitis. I treated her with Duramycin 10. Could the mess be from that? She is still sneezing sometimes. Should I start treatment again? Her vent looks like its coming out a bit, though you cant see it in this picture ..I thought maybe i should gently wipe it with a warm rag, and some peroxide?
