I have posted pictures of my girls, there very healthy and getting big but how? They free range 80% of the day and eat grass, bugs ( we do not have many bugs) and I give them treats like fruit and watermellon and some days spagetti or what we eat that night .but I noticed the feeder just does not go down much. I put a 5 pound bag in it 2 weeks ago and it's still half Of full , are they getting all there needs from the free ranging? There getting fatter, and they very healthy. What's your thoughts??
