Hatching Time discrepancy please help

[Sill]

I guess there is no way to tell which are the brown & which are the A&M? If I get any to hatch can you tell right away or have to wait for their feathers to come in?

It will be obvious at hatching. You will have brown chicks that will stay brown and yellow chicks that will turn white.

day 18 woke up to 1 chick do live chicks huddle around eggs they can hear someone alive inside by any chance? This little one seems very lonely but huddles back & forth between 2 specific eggs when its not pecking at the food or running around. i only floated 3 of our 15 eggs a couple days ago, all passed the float test (I didn't wait for the wobble though it was a quick in & out). I didn't candle so have no idea what to expect. Was just wondering because he keeps chirpping loudly & favouring 2 eggs that are beside each other.
