There are plenty of items on a typical prison menu he can eat without eating “baby cow”, or “blended up chicks” as you put it. There is no need to live off bread and water when there are vegetables, fruit, salad, juice, rice, beans etc. I’m sure this will be pointed out to him and also the limits of what a system will accommodate - dietary or religious needs. Also, his ethics are why he is in prison in the first place so boo hoo for him.
