- Uber for eggs. One household in the hood does all the chicken chores and sale eggs very locally to only some small ZIP code. Of course considering cost on a small home scale, eggs would be most likely at 15% price of shelf ones. Also bigger farmer could not just come and order thousands at such low price because the owner would not have capacity.
- diapers for chicks. If you can invent cheap diaper for chickens then 90% of chicks pollution is gone. you still have to deal with food, water, etc, BUT the major turn off will always be amount of excrement they produce.
Considering the price of eggs today, if nothing gets changed and flus will prevail, these are a billion dollar ideas :)
Edit: unless of course someone is doing that already :) I haven't checked.
