Hen laying ripply eggs

[gar1967]

I have two 10 month old hens. One is a Jersey Giant [black] that lays ex-large eggs. Her egg shells have had ripples on them. When I researched this, it says she might have an infectious Bronchitis.
I am concerned because I don't know if it's possible that I may have given it to her because I have Bronchitis myself or vice versa? She's a very good eater; almost aggressive eater. She will hog treats so my other hen can't get any.
Their water is 1 gallon water to 2 tablespoons apple cider vinegar. I have noticed black smelly stools for about 2 weeks.
Does my hen have Bronchitis and is there a home remedy to help her?

IB is not always the case; and no you cannot pass a bronchitis to a chicken or the chicken to you. IB is something that runs its course, but the chicken will be a carrier for life. If you’re really worried, see a vet. I’m sure there’s a test they can do. But in the meantime, if she’s happy and healthy there’s no reason for immediate concern.
