Possibility of breeding for purple/pink bloom

[kgilmore1]

I have an ISA Brown (I know already a "mixture" and unreliable) that lays beautiful brown eggs with a purple/pink bloom consistently. I was wondering if it was possible to try to incubate and single out the tinted bloom gene? What breed would be best to put with her for that purpose? I'll add pictures but it's incredibly hard to get the total effect on camera. Also every egg pictured is actually a brown egg identical to the ones in the center of the carton but with a thick bloom.

Maybe try photographing against a white piece of paper? That pink carton is throwing me off maybe..

It's so hard to photograph!

I know what you mean!! I applied a filter to balance white and can see it much better. I'll bet it's impressive in person.

I asked this same question in https://www.backyardchickens.com/threads/pink-egg-project-interest.1220962/#post-19537983
I'm very interested in this project, but without others to help it's almost an impossible task!

As with any other traits like humans have found to be desirable for thousands of years, we can breed for the bloom you see(I see it all of the time when I go to the store as most of the brown colored eggs on stores come from ISA Browns or brown egg hybrids.

What you stablish is a Line breeding program, its going to take longer than expected and will require more resources than a regular line breeding program based on feather color phenotypes, but its very much possible.

Breed that hen with your rooster, Keep the best rooster out of that cross, dont keep the pullets as chances are that this bloom is either sex linked or recessive in nature(not all ISA browns display the trait).. That would be the F1 result(keeping cockerels and culling pullets)

F1 rooster crossed back to ISA Hen(Parent line 1) the result of such cross is called BC1(Back Cross to parent line 1) Out of this cross you will keep the pullets and the cockerels, about 50% of the pullets should lay bloom colored eggs

Sounds like a fun project!

I wonder if introducing a rooster from a salmon favorelle or croad langshan would help at all?

I would say that any rooster that lays brown eggs would be best

I have a Copper Maran that has a Mauve or Lavender tint bloom on her eggs. A pretty surprise.
