Blue egg genetics question

[Slothinc]

Sorry to ask this here, I used to know the answer but it is slipping my mind! Any insight would be super helpful!

If a chicken (specifically, a pullet) hatched out of a blue egg, will it automatically carry the blue egg gene? Or if the dad was a white/cream layer is it possible that they will lay a white/cream egg? I believe that if they carry one copy of the blue egg gene, then they will lay blue.

Thanks for any insight on this!! Trying to figure out if one of my girls is laying or not. She hatched out of a blue egg but the rooster laid a cream egg.

I figured it out! She most likely has only 50% chance of laying a blue egg, as I believe her mom was probably heterozygous for the blue egg gene and I think dad didn’t have it at all. So it is possible that she is laying now.

I'm more interesting in your rooster laying cream eggs!

Lol they are just silkies So cream is the standard color for them. But I did have these eggs shipped from someone who had a blue egg silkie mama. I have two hens from her and have been wondering if they are starting to lay yet. I have regular silkies too though, so I am getting cream eggs, and just wasn’t sure if the possible blue egg layers could have been laying them. I will have to try and determine further, since it is possible that one or both is laying now and they may not be carrying the blue egg gene.

It’s the two frizzled satin girls. They are sure cute.

lol sorry I’m so slow…. Hahaha you can tell I am running on no sleep at the moment I want the egg laying rooster as well!

You can check the butts of the pullets if you think they are laying. Little butt hole no eggs, big butt hole close/ laying. Your fizzled girl does have a red comb/wattles so I’d say she may be laying or close to it.

As an update - the girl in the pic with the reddish comb and wattles started laying - and she does have the blue egg gene!! I’m thrilled! I don’t think her sister has started yet, unless she is laying a cream egg that looks like my other silkies. The two eggs on the bottom far right are from her! They are a light green color. The two smaller blue eggs above them are an ameraucana bantam/silkie cross. So excited that at least one of my frizzled silkies is laying with the blue egg gene!!

I have a girl hatched from a blue egg, Araucana father, and she lays pink - _-

That’s crazy! If she came out of a blue egg the mom must have been Bb and if she lays a pink egg then the dad must have also been Bb! Which is strange for an Araucana - I believe they are supposed to be BB. Pink is still a pretty egg though!

I found out today that the sister is laying a regular color silkie egg. So out of the two sisters I have one blue egg gene and one without. Makes sense since it was 50/50 chance!
