I have a little hen who I have posted about in the past. I am not sure of her breeding, she hatched from a large, very dark brown egg, has black skin, four toes, a crest, beard, and yesterday laid a little blue egg.

She is in with my main group of chooks, who are looked after by a lovely araucana cockerel. Although I haven't witnessed any mating, she follows him around everywhere. I am thinking that in Spring I will try hatching some of her eggs. What colour eggs can I expect from any of her female progeny?
 
She is lovely, congrats on your blue egg! I dont have the experience to reliably comment on the genetics but it does sound as if there are some silkie genes in there somewhere. Good luck on your breeding program.

Thank you! I agree about the Silkie, her skin is jet black. I also suspect Marans or Welsummer as the egg she was from was so dark and there must be Araucana or C. Legbar too because of the egg which she laid.

I am curious as to whether her offspring's eggs would also be blue or if they could revert to some other colour, given her mixed ancestry. I have only just started making a bit of sense of the genetics involved in feather colour and I haven't a clue about the genetics of egg colour.

Really? could she have inherited the ressesive blue gene from her mother if her mother had a dominent brown? or doesnt it work like that?
 
The are only two shell colors in the chicken world. Blue and white, the brown on an egg is a coating on the egg shell.

If the Moma hen laid a brown egg she does not have any blue shell genes. What was the father breed?

I am at work now. So will post later......
 
As I said I don't know the parentage, I hatched her from a dark brown egg and she definitely laid the blue egg. It isn't as pure a blue as my araucana eggs. I will post a photo in a while.
 
If she laid a blue egg then her sire (father) was a from a blue egg line or at the least an EE. With mixed breeds like this it's hard to tell what the offspring will lay for color. There are people who purposely breed for olive colored eggs but do this from pure bred parent stock so know what they will get. Pure blue egg breed crossed with dark egg like Marans. What you have is an EE that will be crossed with an Easter Egger. EE's being mixed breeds you've no idea what color they will lay, ranges from light tan, pink, greenish and blueish. And of course you don't know what color egg the cock bird came from.
 
ah I see. So mum would have to have had a blue egg gene with brown coating gene turned on and if dad has white egg gene with coating gene turned off, could she have inherited the dads genes for no coating and the mums blue egg gene?

Sorry for all the questions, its really very interesting.
