So, I know the roosts used to use "Hens" before they were Grouse, and wheat in order to collect eggs. Now, the tooltip says you need one grouse and "seeds" to collect eggs. I tried stacks of all different kinds of seeds with my captured grouse inside the roost, nothing ever happened. I decided that maybe the tooltip is wrong, and you still use wheat to get eggs. I put a stack of 50 wheat inside my roost with one grouse, and the grouse and 5 wheat disappeared and I got 3 feathers, no eggs.
Is it a bug or am I doing something wrong?
