I have had my little girl vet checked, and he said everything seems great but she may be a little underweight. She is now 4 months old, and weighs about 4 pounds, also going through her first molt. My drake is six months old and weighs 8. He is double her size. I know that males are suppose to be bigger but he is huge compared to her. She eats all the time, and when I put out food he is so kind, he let's her go first and patiently waits. So I know she is getting enough food, plus they free range all day. She just seems so small, I have been putting corn in with their feed, and she gets a good bit of that leaving none left for the drake haha. I am just concerned, does 4 pounds sound right?
