I don't have anything to weight him on sadly, my chickens are heavier than himAbout that weighing him bit -- it may be easier if you wrap him in a towel if you are trying to hold him. Make sure you subtract the weight of the towel.
If your chickens weigh more, then he is quite thin. if you have $20-$30, go to Walmart and buy a kitchen scale. Place the scale on your counter in the bathroom, take him in the bathroom, turn on scale, turn off lights, place him on scale. He should stand quietly in the dark.
