Fred's Hens :
Interesting question, but just think about it. If all the grit they've ever eaten did not pass, the chicken would weigh a half a ton!!!!
Of course, like all things, this too must pass.
This is my first time as a chicken owner, and my chicks are only 6+ weeks old, so I did not...
Do the chickens pass the grit they eat? I read that the grit gets lodged in the gizzard, but am wondering if they continuously eat it? Then it must go somewhere? Wears down, then passes?
