Yes, the meat of the avocado is safe for chickens to eat.Can they eat the meat of the avocado?
If you slice an avocado in half and offer it to the chickens, they will eat the meat and leave the seed and peel-- smart of them! (Then again, I'll bet the peel doesn't taste good, and the seed is big and hard, so maybe they don't have to be very smart to leave those parts and just eat the good stuff.)
