How did the first baby bird survive without their mama to feed it?

Put down the weed

What happened then?

Your question is why macro evolution is a philosophy and is not science based.

Noah also lived to be 900, right?

Some reptiles are abandoned at birth. I would guess that evolution has lead to the need to have mothers raise the babies to help ensure the survival of the species.

Baby chicks under the right conditions don't need a mother. Asong as they have access to feed and warmth, they could survive.

That's all I got but I am not currently stoned.

Instincts are powerful. Somewhere deep inside your brain is an evolutionary link to single celled organisms.

The first mama bird was not necessarily a loving mother. Like the cuckoo bird, it might have laid its eggs in a primordial bird/reptilian nest and took off. The resulting offspring survived and became modern day birds.

There was no "first" baby bird. In evolutionary theory, from generation to generation there is no discernable difference., i.e. the differences are so subtle that you can't tell when changes happen. Only over extremely long periods of time can you compare the organism to what it used to be. It's a copy of a copy of a copy, and those that reproduce/survive most are copied the most.

Is this a rephrased chicken or egg question?
