Hi Shedog :)
I wouldn't cut him down on them, just feed him apart so that he doesn't steal the others ;)
All my dogs have chicken wings on a daily basis and they in themselves don't cause constipation with my lot, but if they have real meaty bones (RMB) for their other meal on the same day without any offal or veg mixed in, although my 2 girls cope ok, my boy, the big wuss :D gets constipated. Raw eggs don't affect my lot one or the other, I think each dog copes differently and it just takes time to work out who is ok with what :)
My butchers wont sell tripe to me because of the rules and regs, although they give me all of my offal, RMBs, chicken carcasses/wings ect. I buy my tripe frozen in blocks, my petshop buys it in from a wholesaler especially for me, then I just defrost it and give it to them. I used to be able to get whole fresh tripe from the abattoir and they used to love it but unfortunatly I can't get hold of it anymore :(
