Maybe it's a stretch to post this here but.... Time and again when I read a post concerning crop problems there is always more than 1 recommendation to make sure grit is available. I don't understand that. The crop is simply a storage organ. Grit needs to reach the gizzard where it with the muscular contractions grind the food from the crop for digestion. I have yet to figure out if a chicken has an impacted crop why the chicken should have grit available. The problem is a blockage that keeps the crop from emptying into the gizzard in the first place. Why would I want to encourage grit consumption and create a potentially larger blockage in the crop with a bunch of rocks. Seems to me the solution is to address and eliminate the blockage immediately rather than enhance it. Your insight would be appreciated.
