[Gpdd] Care: How much to feed?

[Lisa]

My boy, Beaker, is about 3.5 months old now, and as I'm slightly
paranoid about his nutrition, I want to make sure that I'm feeding him
well!  Right now, he gets some veggies in the morning, and I also
basically free-feed him a mix of alfalfa and timothy hay pellets.  He
also gets hay at all times.  My question is, is it ok to give him as
much of the pellets as he wants?  He usually nibbles on them
throughout the day, and I give him a refill before I go to bed at
night.  Is this enough, too much, or what?  Beaker is happy and
healthy and I want to keep him that way!

Thanks,
Lisa
