Quote: So all your EEs ended up cockerels?!
What are the chances!
Yes, you can get a green egg out of an EE crossed with a barred bird. Most of the time, the gene for blue shells is passed along with the pea comb gene, so you will have a better chance if your barred pullets have pea combs. (Not 100%, just a higher probability.) However, Dominiques have rose combs, so it would be hard to tell rose from pea until they are bigger. If they have straight combs, then
. Do any of your barred pullets have muffs and beards?
Not sure why those black and white cockerels couldn't be Dominiques. They look more cuckoo than barred. Those guys have 2 different comb types, so it's really hard to say, but the barring is too uneven to be BR. I think they are mixed. I couldn't see enough of the pullets to tell. (If I even could. They are so similar)
Breeders who are trying to keep lines of specific breeds will keep breeding pens of birds and track the development of the chicks, keeping only the ones that exhibit qualities of the Standard (or whatever quality is desired) to keep in their breeding program. Casual breeders, who have some chickens they like and are happy trying to get more chickens they like, will often run the whole flock together and let nature take its course. Then there is always the problem of roosters showing up where they don't belong. The sperm from a "fence hopper" can stay in a hen and fertilize eggs for up to 3 weeks. One sneaky rooster can wreak havoc on the best of plans. Also, once you get several generations out mixing breeds, all sorts of things can pop up. My point is, I'm thinking the person you got your birds from is more like a casual breeder. She told you the possible parental breeds, so I think you can rely on that info. How pure the birds are is another story. Unless you are showing, purity isn't such an issue. It is an issue if you paid big bucks for something you didn't get. Hope you get some green eggs!
