i make flock block also, i used 1 cup of their feed, steal cut oats,
corn meal, cut up apple peices, apple sauce, mashed up bananas, and some frozen black berries.
i dont use to much molasses(didnt know if it was ok for them)
i freeze them in long rectangles and then wrap them up and use when needed. i find if it is a crazy rainy day the chickens get bored faster, so i take out their flock block and let it only defrost a bit, then i break it in half. i put half in one area and the other in a diffrent one. they take most of a day pecking at it. a good healthy treat!
