Buffalo blue cheese chicken Sausages. (First time with chicken)

[RrmyGuy]

Like the title says, I've just had my first run with making chicken sausage. I made buffalo, blue cheese sausages. I didn't have a recipe, I usually formulate my own recipes. I had 4.5lbs of chicken thighs, maybe 1/3lb of chicken beast tenders and about 1lb of beef fat. I used 4oz of Frank's dry buffalo seasoning, 2tbls of course black pepper, 1/4 apple cider vinegar, 4oz of chicken stock, 6oz of Frank's buffalo sauce, 1/2 cup of low fat dry milk, 1 cup of blue cheese crumbles. I did a single grind through an 8mm die. Mixed all my ingredients, then stuffed them into 32mm collagen casings. I love the flavor, the shake sausage is a bit crumbly, but good. The casings on the other hand, are terrible. They're is no snap, and they just don't have a good mouth feel.... I'm thinking next time I'll go with a double grind, and a full cup of dry milk for a better bind. And I'll use sheep casings. Any other sugestions?
