They are so precious! They look to me (no expert) that they are roughly the same age as mine, probably a week or so younger though. Mine were hatched on April 30, so my guess is almost 2 months old. I say they are younger than mine because in the last week the feathers on my BR's necks started to get thinner and I heard them gobble last week. Yours look just like mine did only a week ago. The only thing that could be a vairable is that I have only been feeding mine 22% protein meatbird food so if you have been feeding higher protein yours may be younger but bigger than mine. This is my first time with poults and I just love them- they make the cutest sounds and are so friendly even though I haven't spent time handling them. They come right over when you make imitation turkey sounds- here TuRKturk-turks here TuRKturk turks! So much fun!
