Mothergoose,
Ebay can sometimes be a strange and unpredictable entity. Although I don't own any BCM's, I have been kinda watching the current "trend" in regards to these. It is just my opinion based upon my observations, that your eggs are just about as good as anyones. I think that part of the reason that your eggs aren't getting bid as high as others, is because you actually have TOO much honest information in your listing. You list your eggs, if I remember, as 4 to 6 on the Marans chart. That description is honest and fair, but not what the buyers want to hear. Many other listings claim "7 to 9" for color, and clearly the eggs are not even close to that. Then, there are other listings, where the color chart is not even mentioned, but there are pictures of eggs taken in natural light, with dark shadows outlining them, and the shadows really give a false darkness to the egg color.
I agree with the other posters who say that the eggs are worth exactly what the market will bear, but when it comes to
Ebay, a sellers words and pictures determine the final price. Keep up the good work and don't be discouraged, you may not get rich, but you can't put a price tag on honor and integrity. when the dust finally settles on this "Marans frenzy", the cream will rise to the top, and the reputable, hardworking, honest breeders who are in it for the love of the birds, will still be doing well. I'm still keeping an eye on all this because I do eventually want a few Blue Coppers, or sports to experiment with into some of my Blue Standard Cochins.
Merry Christmas to all
