Coloured egg crosses .

[Hazel feather]

Hi everyone, I’ve decided I’m going to cross my cream legbar roo to some of my hens in the hopes of colourful eggs , I’m not sure what the crosses are going to look like so if anyone has any ideas I’d love to know ! I’d also love to know what egg colours the offspring could lay !

Ccl roo over :

Olive egger ( cuckoo Marans x ccl )
Splash laced red Wyandotte
Light / Colombian Brahma
Black copper Marans
Welsummer
Lavender ee ( she lays a blue / green egg)

Thanks in advance !

They should all lay green eggs. The shade of green will vary.

Thank you for your reply ! I’d be delighted if they lay green !

Adding to this, if you wish to identify the layer:

Crosses with dark layers, like marans, will produce olive hues.
Wyandottes x CCL will produce sage/light greens.
Easter Egger x CCL will likely produce blue/seafoam eggs.

Here's an illustrative overview on genetics. First figure features a rooster with blue egg genes, like your CCL: https://silverhomestead.com/how-to-breed-blue-green-egg-layers/

Egg shells are either white (recessive) or blue (dominant). Brown is a tint overlay.

And, since you are using your DF (double factor) barred purebred? CCL roo, ALL of your chicks will be barred. Since your male has 2 of that dominant barred allele, every single chick should have a dot on their head at hatch and grow barred feathers with only dad's single dominant barring allele per chick. But, if your Olive Egger is hemizygous cuckoo feathered, their male offspring would also have the DF barring, showing much "lighter" barred feathering with twice the white barring to black. If you breed any non-barred/cuckoo'd hens' chicks from your CCL roo, the pullets will be "hemizygous" barred from their dad only. That barred feather allele in the hens could give you sex links if bred to any dark solid colored roos. But I have no idea how the different hens' breeds may moderate the feathering. I've been playing with barred hens and my solid black BCM roo and now have several barred Olive Egger boys, sexlinked! None of my first year's hatchlings have yet come into lay, so I don't know yet what depth of chocolate their BCM young roo dad has given them????

About half of your brown egger hens' chicks, or 3/4 to ALL? if homozygous blue egg hens' chicks will all lay/carry green/olive eggs colors, but if later generations bred, you may not know what they have, and get a wide variety of colors.

I did just hear of a newly available genetic testing that is far cheaper where you can send a simple feather, just like with our hair, and the lab can give a full readout of all the alleles!
