rdobbie, IMO a chicken quarter should be fine for your boys. I have a 50 lb Boxer and a good majority of her diet is chicken - especially chicken quarters. I like them because she has to work to chew it, versus a chicken leg which she can almost swallow whole, haha!
Brynn at 50 lbs gets roughly 16 oz. of raw a day, so quite often I will give her a chicken quarter in the morning that is around 12 oz, and give the rest as organs (liver is her fave!). Remember, to provide some variety. I.e. I give Brynn turkey necks, chicken necks and backs, beef etc. for some change.
Also, remember you don't need to give organs everyday, just try to balance it out over time (I aim for a week). Some of the chicken quarters I buy still have the kidneys attached which is a perk!
I also like the bone to meat ratio in the chicken quarters, I think your boys will love em!
