Making a breed for 5 years now, need a tester, will cream eggs work?

[derBauer]

Hello all! I have been working on a beardless high production, small blue eglaying gamefowl with a pea comb. But now I need to have some o/o homogeneous white birds to test for O/O. Could I use my bantams eggs, she lays cream whitish.

Do you have any other banties that lay White, or a Large Fowl that lays white?

When you say cream, do you mean light brown, or tinted?

I mean tinted, I just checked my logbook and I have 1 other standard mutt hen that lays tinted.

Tinted may work if you have nothing else. The outer portion of the egg will be a light green, & the inside of the egg shell should be a light blue.

Thanks!

Yes you can use tinted. Or white or brown.
If you're just test breeding anything other then blue or green will work.

I'm still learning about egg color genes, so if I'm wrong on anything, someone else who knows more, should correct me.

Thanks!

You're welcome.

I just arranged for tests to be run in Germany on @20 of my chickens to see which are heterozygous and which homozygous for the blue egg gene at a cost of $30 per test. While test matings are a viable way to find O/O birds, the cost of running these tests is low enough and will save enough time that I can justify the expense. You might consider doing likewise given the time you could save.

I have 5 roosters and estimate that 1 is O/O, 2 are O/o, and 2 are o/o. For my hens, all have been laying for several months and are known to lay blue eggs. Based on egg color, I think 4 or them are O/O and the rest O/o. Just getting rid of the o/o roosters will make a dramatic improvement in numbers of blue egg chicks in the next generation.
