Dr. N.W. Walker (D. Sc., Ph.D.) claims that you can use sorghum seeds to get ...

Some years ago, while doing research on the properties of sorghum seed, I discovered that a genetic female hormone was quite prevalent in these small, glossy kernels.

I had a feeling that this sorghum hormone could, perhaps, influence the percentage of female birds hatched, and-to check this "hunch"I set up an experiment using zebra finches ... which (because they regularly hatch up to four eggs a month) seemed the best choice available to me.

Before I began the research, these birds had hatched out a predictable half-and-half mixture of male and female finches.

I decided to keep a full dish of sorghum seeds in the aviary at all times and watch for developments.

At first the birds didn't show much interest in the new food, but-in the course of three or four weeks-they began to feed on the sorghum before moving on to their regular feeders ... and they followed this pattern both morning and evening. Then, after two or three months, I began to notice an increase In the number of female birds hatched.

In fact, by the end of the first year of sorghum-supplemented feeding, my finches produced close to four female birds for every male hatched!

I'd like to know how many generations he followed, and if there were any other effects- were all the females a healthy and productive as normal birds, not fed sorghum? After 10 generations? 20? I'm going to do some more reading into this.

That is Dr. Norman Walker, the juice teacher.  Perhaps there is something in his writings of what else he found.

I suspect new trials will have to be done.
