Our chickens may be getting fat. They no longer fly and the ground shakes when they run past. We give them a scoop (about 1 to 2 measuring cups) in a little heap in the morning for the start of their day. We only have 6 bantam chickens and a few chipmunks take the leftovers. They have free range of our 100'X100' suburban lot, including hills to climb. We feed them laying feed, they are all 1 and a half years old and lay about 1 egg a day each. Actually, they dont eat much of the feed. Their gullets are full of greens and bugs by the end of the day. MUCHO CICADAS this week and those white grubbs that would be beetles next year, and a few big long katydids or grasshoppers. They cleaned out our blackberries. ALSO, they ate billions of those shiny green japanese beetles. With such an active lifestyle and a seemingly Atkin's style diet, I wonder if the corn/grain scratch could be making them fat? Any advice would be greatly appreciated. With this strange weather, I doubt this winter will be cold enough to withold greens and bugs from them, so I worry a little that they'll continue to get fatter for the next year.
