super fast growth

The splendid babies are growing at super fast speed.  The 3rd baby in the clutch of 4 is hatched and hopefully the last egg will hatch out soon.  It's only been 7-8 days since the 1st baby from the clutch of 5 hatched, but I have already been able to close band the oldest 2 babies today.  The 1st baby is about 4-5 times the size of the youngest baby, who still appears to be well-fed so far.  The oldest babies are starting to get the starts of pin feathers over their white fuzz - I think they are almost doubling their size each 1-2 days.  The parents are both busy making sure their babies are well-fed.  Mealworms and veggies as well as sprouted seeds and millet spray are on high demand.
