Does anyone know of a commercial or DIY solution for this? I've done some searching and found a paper from a University that does something like this, but didn't find any other solutions. The solution in that paper seems complex since it requires a custom lay box solution. It seems like something I could build by putting a cheap band on each chicken leg and then putting a scale that reads those bands in each nestbox. So it would basically scan the tag on the chicken and then record weight before and after that chicken sat in the box. Then I could determine if it left an egg in the box. Then I'd upload this data to your smartphone so you could see how many eggs each chicken laid. That said if something like this already exists I don't feel I'd need to reinvent the wheel. If nothing like this exists would this be something people are interested in me putting on Kickstarter? I've done several successful Kickstarters, but nothing related to out chickens. A really rough guess at price would be $70 per scale with a bunch of the chicken bracelets included.
