Genetics Experts - Can someone please explain HOW this happened???

Are these chicks the only kind that came from the black parents?
They look columbian restricted, the dark one may be melanized and columbian restricted, like a lakenvelder.

Your animals may carry wheaten or another recessive e-allele, but then you also should get 75% solid black ones.
Small numbers never obey chance...

The dominant E or E^R alleles suppress columbian restriction.
Not that you need a restrictor to get non-solids if you have wheaten in there.

Hi Henk, so glad you chimed in. Yes these are the only chicks from this stock. The original parent stock of the now parents of these off colored chicks I still own. My blacks have only produced blacks when bred together which is where this black hen is from as well as their black rooster. My splash rooster when bred to black hens is producing gorgeous laced blues. When bred to a blue hen he has produced all blue and splash offspring. That is where their splash rooster is from. I have hatched many from the original parent stock and never get anything but what should be... So in my mind the only two results they should get in offspring by the possible crosses would be either solid black or blue chicks. She only laid and set on 4 eggs, all 4 hatched. All 4 are the colors you see in the pics, no blacks at all. One or two is gold with a very light cream color chipmunk stripe, one is solid gold and the other is the dark body/gold head. Any thoughts???

The reason that you didn't get any may be very simple.
If one of your breeders is purebreed for the dominant e-alleles E or E^R you won't get any recessives.
Your neighbours should get solid chicks if they bred any more.
What chickens do the other neighbours have?

So what pattern should we expect these offspring to mature to? Also will it continue to breed true or just an anomaly?
