So my family bought our chickens about 2 weeks ago and love them... BUT I am unsure about why my hen is laying a brown egg. See we bought a flock that was all laying and full grown to avoid raising chicks inside, however we are supposed to have 2 Easter eggers, 2 white leghorns, 1 gold lace wyandotte and 1 rumpless and tuff less araucana (sorry if I misspell that). He told me we should get 2 green eggs, 2 brown and 2 white and we do, but I'm extremely confused about why our araucana lays brown eggs (sometimes with speckels). As I understand it she should not lay brown or white ever if she's a purebred... so why the brown eggs?
