He is a big boy. Atlas and Lady are about 8 months and they are some of the largest birds I've ever had. Atlas is probably around 8 pounds and Lady can't be far behind even if she's just a sexlink pullet.No, I don't know because I haven't weighed him. He's not full grown yet as he will only be 5 month's old on November 2nd. He's already a big boy though! He's taller than the bottom bar of the horse panel there in the picture.
