Flock blocks are not real high in protein. I bought one in the winter it gave them something to peck on. I'm getting away from to many treats. I'll give mine some boss here & there. During the summer I give them veggies from my garden no problem. But giving to many treats reduces there protein intake from the feed your feeding. I've never been able to figure out the no more than 10% treats rule. So, this time of the year I let them free range & find their own food. They always have feed available in the coop along with fresh water. I will always give them meat because it's high in protein. I want to make sure they are getting plenty of protein not a bunch of junk food that lowers their protein intake that's provided in the feed that I provide them.
