broody bantam and 28 days

[white ninja]

my ameraucana rooster gandolph died several weeks ago some how and i saved some of my RIRs eggs that are fertile from him to hopefully brings his great genes into the next generation. my bantam frizzle hen Pheasant is going broody with the eggs for up to 28 days now, thought they'd hatch at 21 days ?? i hold a light up to them and see a dark spot unlike a fresh egg without a dark spot whats going on there?? HELP ME PLEASE

ive got a bunch more questions about this dilemma but keeping it simple for meow. ty

If the eggs are on day 28 of incubation, they are non viable. Sorry.
