The Olive-Egger thread!

I HOPE you are right! I have this theory that female chicks scratch more than males. Anyone else notice a correlation?
He is right, female barred covered by non-barred roosters creates sex links. My White Leghorn carries barring under dominant white, when crossing a black cockerel I noticed that the males hatched out with white/yellow legs but the females hatched out with slate/black legs - my sample was small so I want to try this again in the future. Both hatched out white with black spots, the males obviously were more white/less black because of barring. Barring also suppresses shank color which is my theory as to why the hens hatched out with dark legs and the cockerels hatched out with yellow/white legs.

I haven't noticed any correlation with scratching etc but then I haven't thought to look for that either. It seems like the tail feathers grow in at different rates male vs female but my sample is admittedly quite small and I haven't truly studied it.

I have a barred roo over a non barred hen?
 
Can olive eggers have offspring that lay blue or mint green eggs? Or is there only the chance of olive eggs? I have one OE hen and the two EE's that are almost six weeks old. The third six week old chick is a EE roo. I wonder what color of egg possibilities there are with those four. The other roo is a Dom.

they become more like EEs after the first cross--A rainbow of colors becomes possible.
 
The egg rainbow is affected by each bird's DNA and what they pass on.

So some birds wether EE or OE will be Oo (Blue Gene + wild gene), thus producing either a Blue or Green egg. A bird that is OO will pass the O gene to all offspring but an Oo has only a 50% chance of passing the O gene. Thus an EE that is Oo bred to an OE that is Oo statistically has a 25% chance of producing OO, 25% of producing oo and 50% of producing Oo chicks.

The browning genes that produce the tint (that makes the blue become green) are a separate group of genes some that can work together to make eggs darker but others can actually counteract each other, thus a dark egg breed bred to another dark egg breed can actually produce hens that lay lighter eggs. (I have read a guess of anywhere between 11 to about 13 genes that make "brown"). The "brown" genes give you all the shades... and just to hurt the head more some white egg breeds such as leghorns carry special genes that prevent the brown genes expressing... thus if you cross a leghorn to a brown layer you could end up with hens that lay white eggs, in the case of a green layer you could end up with white & blue eggs depending on the hen's DNA.

The only way to know that your rooster carries the O gene is to test breed him to hens you know do not carry the O gene (white or brown layers) and wait to see what his daughters produce, if you get blue or green eggs you know he has the O gene. If he consistently produces such offspring out of wild type egg hens (oo) then more than likely he is OO. Note however if you get blue/green layers and brown/white layers as daughters than he is Oo.

All white & brown egg layers are oo.

You can figure out hens similarly, if you breed a roo to them you know does not carry the O genes aka wild type oo bird and that hen produces daughters that always produce blue/green eggs than more than likely she is OO.

So Green is Oo or OO plus browning genes minus any brown inhibiting genes. Blue can be Oo or OO but either lacks the browning genes or has browning inhibitor genes that prevent the expression of the brown genes.


I hope this helps...

Thank you so much for taking the time to explain....It's difficult for me.
