I have 6 pullets between 4-8 months old - 3 Amaracaunas, a Cochin, a Silkie and an Olive Egger. They have crumbles available at all times and then once a day they get about a quart of a treat mix I make up with black sunflower seeds, cracked corn and mealworms. They are in a chicken tractor so they also have pretty good access to fresh grass. My question is, do they need a flock block to prevent boredom? They don’t get to freerange so I wonder if a flock block would be helpful in preventing boredom. I’m not very handy in the kitchen so I would buy a commercial flock block as opposed to baking something for them. Your thoughts?
