Chickens not breeding

[Extinction]

As my titel says, my chickens wont breed anymore. I have 5 hens and 5 males all grown up. They wont breed for some reason. They lay eggs, but unfertilized. Temperature is 24 degrees, which is fine. They just stopped breeding for some reason.

If they're all related, that'd be why. If they're not, you may need to allot them bed spaces (close to one another). I haven't tested this, but I've been told that helps.

Edit: Beyond that, it might be a bug, if temp/food isn't a problem.

Okay yea.. they are all related to eachother. Seems like the automated breeding with colony manager is broken at the moment, because it just auto kills your unrelated animals, which means that you end up with a lifestock gone.. Well that means that breeding lifestock is pointless for me, i hate the idea of micromanaging every aspect when i can just assign a hunter, hunting all the emus which makes my life 20times easier.
