I am well aware of chicken math, having been a victim myself, but I am now experiencing something completely different! For 3 years now, I let my broody hatch a few eggs. 1st yr = 2 roos, 1 hen.....an adult hen died later that summer, 1 roo ran off 2nd yr = 2 roos, 1 hen....an adult hen died later that summer, my old roo died and the other new roo was given to a neighbor this year = 1 hen.....an adult hen died then a month later = 1 hen ...and another hen just died. All the hens that died were less than 3 yrs old. I know that there is a "cat vacuum' where if you have 5 cats and you get rid of 2, then 2 more will mysteriously appear to take their place. this is well known about feral cat colonies. So now I'm thinkin' maybe I have a reverse vacuum. I'm destined to have 10 hens and 2 roos. Everytime I hatch a hen...a hen dies before the chick is even half grown. I just thought this is weird and wondered if anyone else had reverse math going on?
