I just had a similiar problem. First it was the men, not the women who didn't wish to work. Yoki, Willow and Sage were awesome, rarely said no. The guys; sweethearts, but i couldn't get tthem to work a bit. It wasn't until it came time to clear the lagoon that Seth and Juno got busy. The ladies had three babies apiece with the men and then I found that Sage and Juno, Willow and Seth preferred each other's company. Yoki jusy wanted be left alone and researh.
Finally the tribe got up to 21. Then all hell broke loose. First the chicken poxes that weaken Seth and Willow. A flock of Parrots wiped out the berry bush and then a balmy summer molded the crops and everyone was sick. We laid first Seth, then Willow to rest. Locusts came and wiped out newly planted crops and stored food. They tribe couldn't work hard enough. Everyone was getting weaker and weaker. We lost Juno to another chicken pox outbreak. The tribe, dispite my best eforts was dying. The next morning, only Spice 46 and her half-brother Mazi, 33 was left. Spice was burying her husband Boaz; they little girl Zippoarah had just died, age 5. I had to decide whether to let the tribe go on since both Spice and Mazi were weak, or go for 3th farming techs points and see what happen. So, I took the Tech points and Spice, a master famer found quickly the magic fish, while Mazi continued to bury their family. Afterwards, crops came in and they were also able to fish. once I had the food bin filled to 1000, I decided it was time for them to mate. The first son was Hope. Their health slowly began to improve. The second son was Promise. One day Mazi began sick and while Mama was nursing, it was 4 year old Promise who healed his daddy. The next child was Blessing, a girl. Then another girl, Simha (Joy). Twin girls were also added to the family; Lily and Jasmine. Two years after the twins birth, a cargobox was found by Blessing. Two twin boys, named Moshe and Joshua. Sadly, with a nursing child, Sage died. But the tribe was saved. Hope and Blessing married, Promise to Simha. Lily to Moshe and Jasimne to Joshua. Mazi played the very happy grandpa. Sage lived to be 65, Mazi 67. Before his death, Mazi passed the tribal leadership to Blessing; it was her birthright. Hope passed away just as the temple was being rebuilded. Promised while the treasure was being dug up. Simha died shortly thereafter. Blessing grieved the deaths of her twin sisters, born together, died together at 79. Blesing lived tto be ninty, passing the leadership to her eldest daughter, Sage. Sage's daughter, Ebony gave birth to the Golden. I told you this story to say this; hang in there. You may be quite surprised what your people come up with.
