Help candling remaining eggs

[RochfoKev]

Hi again, hatched 18 eggs and 1 pipped so i am really pleased as this is my first time hatching

I have 5 eggs left on day 22 which have not moved or pipped, 4 are Araucana/Cream Legbar and 1 Black Minorca

1 egg i candle and looks clear so i can rule that 1 out

2 i can see the are sack intact but irregular shapes with 1 i think red blotches

2 i can see the air sack intact with and even dark mass around it

is there any links or advice so i can know what to look for?

Could'nt get a good photo to post, sorry

Thanks for any advice
