Recently came back after a 2 month ish break with a new king. He has the plumage patches mutation

I did a big crb project with around 35 lionesses, and I didn’t get one 3-cub or 4-cub litter. This was super unusual as id always get at least 4 large litters with 30+ lionesses. I also only got one plumage out of 45-ish cubs when my old king’s pass rate was about 1/25. But this could have been the crb so I brushed it off

Recently did a 30 ncl breeding, no crb. Plumage rates were normal but only one 3-cub litter

Additionally I sold out of stud slots pretty quickly, none of them got a plumage which is only a little over normal odds, but once again no 3-cub or 4-cub litters

Did something happen or am I getting incredibly, incredibly unlucky?
