Too many double yolkers in brown coturnix

[veggiecanner]

I am trying to save up enough eggs to incubate a set starting next week.
I am weighing each egg, and only saving 13 gram or heavier.
one was 17.5 grams. I tried to write on it with a ball point pen and punched a hole in it.
Which turned out to be a good thing cause it was double yolker.
Another egg That I rejected for some reason , I decied last night to open to see if it was fertile was a double yoker. And several we ate before I started saving were double yokers.
What should the eggs weigh from quail that are 10-12 week olds?
Is there a way to stop producing so many double yokers?
I just switched from Purina starter feed to Layena. Will that make a difference.
I am not so much in to the quails for their eggs. And prefer eggs that I can incubate, for chicks.

An average quail egg is supposedly 9 grams, is there a particular reason you're only selecting very large eggs for incubation?
With ours I have noticed anything over 15 grams is either a double yolk or has a single double sized yolk, which seems like it wouldn't be great for incubating either.

Also I have seen our smallest hen lay a couple of our largest eggs, so I don't use egg size as an indication of what genetics or chick size I would end up with in hatching.

I don't know about encouraging fewer double yolks, but if there's a way I'd love to know too, one of my girls is pretty consistent with them.

Cheers,

I am selecting 13 gram eggs because a seller on e-bay said she sent only 14 gram eggs. I figured I was just starting so I couldn't expect them to be that big. My hens are still pretty young any way.
I asked for advice on several forums about it and no one seemed to have any better ideas about it than I did.
As far as 9 grams I've only got 3-4 that size. the rest have been 11 grams or larger.
I would like to figure out how to tell if they are double yolkers though. That way I could eat them or use them for chick feed.
I have a few less than 13 grams in my collection , because I need a few chicks to provide hens for one of my roos. I am taking a gamble on those being fertile since the hens have just started laying.
Are the 9 gram eggs you getting from jumbo cotunix?
I am still trying to deceide if I have jumbos.
I just weighed a 8 week old roo this morning and he weighed 1/2 pound. I will weigh some hens next week. but I don't want to upset them and take a chance they won't lay the eggs while I am saving up for incubation. But by looking at them I think they have to be twice that size.

The 9 gram number is actually just from what I've looked up. Mainly from finding nutrition information when I was hunting down carton stickers. All of the one egg serving sizes were for a 9 gram egg.
I haven't weighed our hens but they vary a good bit in size, our eggs are generally more around 10-11 grams.
Our birds came from a school teachers mixed hatch and a guy breeding quail in his back yard, so I'm sure we don't have jumbos.

DO NOT WRITE ON THE EGGS WITH A PEN OR MARKER. You are poisening the embryo. Use pencil only. Myself-I don't write on quail eggs. Why do you need to? If you are keeping blood lines seperate-make little cages for the incubator.

Where did you get that information? That is what I was told to use.

I just have a batch hatch and all the eggs are 14-16grams. My quails have been laying 12-16 grams. There are couple under 12 grams and larger than 16grams. If your quail only laying 9 grams, it is consider small.

As I said, that's not the size I'm getting, that's the average or baseline size based on every nutrition fact sheet I've found for a quail egg. I have one bird who consistently lays 16-19 gram double yolkers so my few birds are not a good basis for average size anyway. My birds have not been laying long or that consistently either.
