Titanium Hen is one of the worst if not the worst building in the game. Costs 4000eggs Uses 50fish 20oil seeds to make 1 titanium ore. I get the fish as people complain that everyone has too many fish but 20 oil seed for 1 titanium ore? What a terrible deal.
Removing oil seed as a requirement from it would make it usable. Or change the oilseed for a different resource like bread or planks.
