After monitoring my coops closely for about 24 hours (real time), I have observed that my hares get to 10 then die of old age. Of course our server has the animal settings on default so it may depend on the server configuration.
I will also mention that neither my hares nor chickens have bred.
/ My chickens produce eggs to harvest and the coops do need cleaning from time to time but nary a newborn chick or hare to be found.
My main chicken coop is actually stuck at 17 chickens - I cannot put in any more nor will they fill it themselves. They will die off and I can refill to 17 or wait and hope they will breed but for some reason 17 is the maximum of that one coop.
And the main hare coop has always had less than 16 hares in it and as few as 11 but still no breeding.
My small animals are feeding and pooping regularly but simply not breeding.
P The coops are claimed by my character and have been for more than 24 hours real time. Farming is at 100, Animal Lore is 68 (would be higher if the durn animals would cooperate), and my procuration is now at 84. Their food is of quality 61-67. What am I doing wrong? Why won't those small critters breed??
