I bought some of the fine indoor bird grit at Wally World and put it in a free choice container. I have some birds that have to be older than some others, some are puff balls and others are much larger and very feathered. I decided to add some fresh veggies diced up on the menu. They have enjoyed that thoroughly! I read here if you start anything other than chick starter add grit. Well, I have 77 peepers and they have gone through the whole box in two days! Is that normal? I thought they would peck just what they needed. I'm hoping they didn't just gorge themselves on it thinking it's just lousy tasting food. Ideas? Thoughts?
