Thank you all!
The two oldest babies came our of the nest and are perching! They are also trying to eat!!

The youngest baby was in the nest itself, after a few seconds Bio came in and fed him and left. Then, Marshmallow came and plucked the head. I got so frustrated that I put the youngest baby in the cage and took down the nest.
After 30 mins. I go outside to check the mail and guess what I found...DUMMY EGGS!! I ordered 4 but I got five! I put 4 in and it instantly tricked Marshmallow and Bio.

The whole Saturday, Marshmallow was trying to mate with Bio! I think I see an egg bum

Marshmallow was in the middle of a mate a couple of times today. There was a time today where Marshmallow was doing the hen mating stance for literally 1 minute, Bio ignored her and ate food instead to feed the chicks, I'm so proud of him!

I also didn't have to feed the chicks once today

it looks like they are doing a much better job.
That was a massive update! Now for the massive photoshoot that I didn't upload for two days straight, not including today's
