What causes shafting
crystalcreek:
I have a chick in my growout pen that is black/lav split that has brown shafting. What causes this? Is it lack of melanizers on extended black? I remember seeing two chicks at hatch that seemed to have more reddish-brown colored down on the face than the normal black down seen in a lav split chick, I\'m pretty sure this is one of those grown out. I\'m also pretty confident that I can cull out this issue easily in the black chicks but what about the lavs? They are diluted so it would not be so obvious. Thanks in advance for any input.
John:
I believe lavender should be based on Extended black (E) at the E-locus and that the brown shafting and face color of the chick indicates it is probably birchen (E^R) based.
Also, I believe they should be Silver (S) at the S-locus rather than gold (s) and the brown/red colors indicate your chick is gold (s/s).
Tailfeathers:
Could someone please help me and define what is being referred to as \"shafting\"?
This subject came up in a previous thread (see \"Light vs. Dark Blue Wheaten\"). I posted what I thought shafting was & asked if I was mistaken. I never heard anything. Then I bumped the thread after checking my SOP but still didn\'t hear anything.
So is this \"shafting\" something different than what the SOP is talking about??
God Bless,
crystalcreek:
What I am referring to is a black feather with a shiny brown center shaft. It is especially visible in the breast area.
I can post pics if necessary for clarification and thanks again for helping me understand this. Any input is appreciated.
The chick will be culled, but if there are issues with the parents I need to know that. Especially if my whole \"eliminate the slow feather gene\" plan hinges on one bird. Thanks
Jean:
This bird has shafting:
It is very ingrained in to the silver line. When I started my project, I had black birds with shafting pop out in the first cross.
