Here is a short version of a key statistical biologists look at hens and poults and is Based on various S E US biologists input From studies in various southeastern states: Out of 100 hens. @80 will attempt to nest. Only @35 per cent of these @80 attempts will have a single chick hatch. Then only @22 % of the @35 above will produce even a single chick to live one month. So @7 % is the average of ALL nests that will produce at least one CHICK TO survive a MONTH. Smaller % number Of that 7 % that ever see the next spring. That’s how delicate the flock growth and decline balance is. Further The chances of a Jake breeding successfully is remote. The biologists say Less than FIVE PER CENT of jakes are even capable of producing viable sperm in volumes to fertilize a clutch with a hen. Maybe that is why jakes reserve their fun to plastic decoys?? The podcast I referenced in a post a little higher above will give a lot more details on the information I attempted to summarize here.
