When will a major U.S. supermarket sell “no-kill eggs” in at least 25 states?

Chickens are generally either bred for egg-laying performance, or an ability to fatten and grow quickly. While both males and females are fattened in broiler production, there is currently no economically worthwhile use of the male offspring of egg-laying chickens, as these cannot lay eggs. Therefore, day-old male chicks are destroyed in the layer hatchery (Krautwald-Junghanns et al., 2017).

As the red blood cells of birds possess a nucleus, they also carry the genetic sex information. Using spectroscopic techniques, the sex of an egg can be determined three days after it has been fertilised (Galli et al, 2017). In egg sexing of a chick’s sex while still in the egg is might reduce the number of male chicks that are killed shortly after hatching.

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
