It looks like Auburn had or has a research study that started around 2015 but I cant find where any data was ever published or if the research stopped or if its ongoing. Would be interesting if we could get real numbers to see if there was an actual decline in population and if so how big was or is it?

Glad so many of you are seeing poults, the one thing I saw in research data was the number of poults per hen is down to just below 2 when including the hens with 0 poults. Not including the hens with no poults the number of poults per hen is about 3. Those numbers seem low to me, I wonder if those are poults that reached adulthood or babies seen with the hen at any time.
