Marcy~ Eye color is something that is not as explored as other things genetics related. Many things eye color on chickens and bird cannot be explained. I hope others that know about eye color genetics comes by and shares their wisdom with us.
I read that some darkness can be caused by melanizers and some darkness can be caused by an illness called Leukosis, (hope I spelled it correctly).
Question.....Are any of your hens over melanized? Show very little copper?
I have bred a dark eyed female to a male with correct eye color and have received good results in offspring eye color, with only a small percentage having a dark eye. I once tested a dark eyed male over a female with correct eyes and got a larger percentage of dark eyed offspring.
I usually cull dark eyed birds from the flock, but if they have something too good to toss out, I will test them to see what I get.
I currently and still have one dark eyed female that I use because she is a nice representation of a Marans in all other aspects. I have been breeding her for 4 years and she is my only original pure Davis bird that I have left. She will not be leaving any time soon.....she makes some very nice babies, she is the mother to my Lil' Bill. I have now been crossing her back to Lil' Bill for what now..almost a year and a half or slightly longer and have raised several of their offspring and they have had the correct eye color that they get from Lil" Bill.
Hi PInk, well as we have discussed so much, one must pick their battles with these Marans, and my first battle was to get the color back in the pullets. My founding stock were overmelanized, only one hen with a very slight amount of copper, so all the ones I kept have fair to good amounts of copper hackle feathers. All the cockerels I kept have good eye color, so I guess I will just do some testing matings and see what happens. It takes so much time to know since their eye color changes late in development. I still have 4 of the Black Copper cockerels. I butchered the founding male and the last 3 of the founding hens on Thursday. These youngsters look better than the father and the mothers and those older hens were on their third round of being broody this summer---so sick of that and with the cost of feed being so high, I can't afford freeloaders.
It's been pretty hot here the last 4 or 5 days: 95-95 degrees, no relief from the sun, ugh. Hard to get anything done outside. I've got to move some sand into my condo pens--the sand pile is quite a ways away from the pen, so one wheelbarrow at a time. Then I will move a few black copper and blue copper pullets into individual pens to see which ones are laying the darker eggs. That will be my next deciding factor on which pullets out of the 17 to keep! I'm thinking based on earlier discussions from Vicki and others that I'd be best off at this stage to mate the best blue copper pullets to a black copper cockerel instead of a blue copper cockerel. I still have all 3 blue copper cockerels--sorry haven't taken new pics yet--but the younger two still have dark eyes. The older one has good eye color but I'm not as keen on his tail. With so many pullets to work with, I could do one blue to blue mating just to see what happens. Feed cost and space to raise them are my biggest concerns.
