Please tell more about eating them???
The half grown ones are best but I have had full grown ones that were good too. Avoid touching the scent glands, wash your knife and change your rubber gloves after skinning them. I like to quarter them and cook over coals. Brush a little of your favorite barbecue sauce on just before done. I have heard all the stories " they stink - covered in fleas - taste terrible" But that's not my experience.
I have cooked dozens of them I shot in West Texas and they were all good.
btw - They eat prickly pear cactus.
