RedBank to make the thing easier for you I m going to tell you a double yolk laying pullets is not a breeder for sure .
all you flock are fine . So that pullets in genetically incorrect .
Selective breeding . if she doesn t perform than is not a true breeder.
catch her and put her with your layer flock . Don t take risk .
chooks man
I didn't read this post before replying to @RedBanks . I have noticed that my mutts lay double yolkers. they come from a junk breeding place (roo +hen=chick). I have also noticed that those birds don't live long, 1 year and they start having health issues. they lay even more than egg laying hybrids. I will never get them again.
