Hi! I have a source for free fresh cottage cheese. I can have 3 (24 oz.) contaniers per week. How much and how ofyen would you feed it to a flock of 25 chickens ( 2 roos, 23 pullets, 17 of those pullets laying--the other 6 a little too young yet) They LOVE it, but I don't want to overdo it.... on ther other hand, it has lots of protein and calcium....
