There were 6 cockerels that hatched at the same time and while they have barring, there is some serious leakage. No one would ever mistake them for a pure rock.
This girl looks like she is.
I found this interesing.
Maybe because roosters are more colorful that's why there is all that leakage...
I have a young hen that looks like a pure Plymouth Barred Rock, but she is not.
The father is some mixture that has the gene and he looks relatively close to the breed but none of the hens who could had laid the egg look anything like a Rock.
Is this something that is very rare or fairly common...
