My Redfoot (Peabody) was also an April hatchling. I got
him in July so he would have been about 3 months old. He was
50 grams the day I got him. By the end of December he grew
to 150-200 grams. He grows in spurts. He is now 3 years old and
about 2 lbs. He does not seem overweight.

I don't have his growth chart in front of me but he seemed
to gain about 50 grams/month that first summer.
