This is highly incorrect.
It is more likely that a chicken confuses grit for food if the grit is covered in feed dust from industrial preparations because they can taste the food dust on the grit surface. Chickens CAN taste. They know the difference between scratch and gravel just by tasting it. They also eat a lot of grit.
I thought my chickens had enough grit from free ranging, but they always made several trips on my sidewalk just to eat the leftovers of the construction site. They would eat cement, dig holes all around the corrugated tubing looking for gravel and sand, going as far as displacing some self-locking tiles and, most annoyingly, pooping all over the sidewalk and cement floor.
So I ordered a load of construction gravel, and got a whole pile unloaded in the farthest corner of my property, and my chickens would spend hours digging and eating from that pile of gravel. A trip to the gravel pile is the first thing they do every morning.
And more importantly, my chickens are not destroying my cement floor anymore.
I throw scratch and leftovers on that pile of gravel and never had a problem in years. And it's not even grit for birds, it's construction aggregate. uuuh... what a horrible chicken owner I am!
Chickens are not dumb. Let's just quit this whole grit terrorism
unless someone has *actual proof*, including necropsy photos, of a chicken killing itself with feed grit.
Nobody posted any real proof of a dead chicken stuffed with gravel on this post.
The only way a chicken could die of overeating gravel is if this chicken had a disorder called
"pica". All animals can be affected by pica. I know of cows with pica (they eat stones), cats (they eat mostly fabric), and dogs, and people of course. I've read on this forum of a chicken with pica disorder who would eat anything except food. That's the only case where a chicken can die from overeating stones. Pica is a deadly disease for all the animals - and persons- it affects.
This will be my last reply to this thread 'cause I really have nothing else to add. I just want to say, do your own research before getting scared of things that shouldn't be scary. It's often a false alarm.
