Chickens, along with birds in general, do not ‘pee’ in the sense that they do not release a liquid urine. Instead of peeing out urine, chickens excrete a urine product in the form of white paste that they pass with their stool!
Yes, chicken eggs do come out of the same place that their poop comes out of, but it is not that simple. Fecal excrement and eggs both exit from the cloaca, however, the cloaca cavity itself has 3 different chambers within it.
Most eggs come out of the chicken clean, or at least not covered in poo, as long as the chicken is healthy. There are a few things that you can do to make sure you are collecting relatively clean eggs from your coup.
Occasionally, a chicken of any age can experience vent gleet, also known as pasty vent, pasting, cloacitis, or pasty butt.
If you notice your chicken showing any signs of vent gleet, there are a few things that you can do to try to resolve the issue.
