My pullets are finally laying regularly; We sometimes get 3 a day between the 2 pullets and their broody. A mystery has begun in the coop; Three hens, four eggs colours! The large pale egg is from the broody, the other are new from the pullets. the dark small ones are layed with a lovely white lace on top that disappears fairly quickly with moisture and the speckled ones are darker and more speckled that the photo suggests. The speckled ones are also typically larger, but definitely new since the pullets have been laying. I know the extra colour isn't from my roo! I understood egg colour was genetic and fairly consistent, but I'm a rank newbie. Any idea what's going on here?
