I have learned that peas don't eat like chicken,guinea,geese or ducks, the peck a little and then turn arond and gobble up their poo
If you are seeing it eating even just a bit he is proble doing it when you aint looking.
It does look small for 3 weeks featherwise and crest but it looks healthy in the photo so mabe it's just going to be a small pea, mine are different sizes, my cameo was way smaller than my other babies but she grew just as big as the rest of them in time.
Eggs are good for them, mine still get them a few times a week, sometimes they eat them up other times they pick at them and wonder off to find something else.
