My MIL bought these chicks from a local farm store. She was told they were White Leghorn Pullets. Well we now have 2 roos and 1 pullet from these three chicks and I am beginning to think they are not leghorns at all but Delawares.

My other chicks are Black Austrolorps that are 17 weeks and EE that are 16 weeks. I am seeking out other opinions because I truly don't think the guy at the feed store had a clue. Here is a picture of one of the roos: Here are pictures of the hen: I know about the ear color trick but honestly I don't know what I am looking at so here is a closeup of her face: Thanks for the help! ETA the chicks were all yellow no black on them until they started to feather out.
