I was just reading another post and they were saying that a rainbow layer mix from a hatchery includes birds that lay brown, white and blue/green eggs. Is that the way it works? I orderd 15 Rainbow layers from Cackle and this is what I've identified: 2 SLW 2 GLW 2 Buff orps 2 EEs 2 RIR or NHR 2 BA (I think) 2 BR and 1 brown bird that resembles my Partridge cochins but with no feathered legs. Its a very nice mix, but I don't think any of these lay white eggs~~~and I didn't even think about it til now! What's up??
