I'm having a few problems and I'm not sure if it's me or the game! I bought a chicken but I can't put grass or hay in the trough of the coop. It just wont seem to let me! Is there some different action/key I'm meant to be using or is it just not working? Also my chicken disappeared. I thought it died because I couldn't feed it but then I read that they don't die, they just don't produce as well. I had the coop roller door closed the whole time and have looked all over the farm for it too. PS where do you find copper bars to build a silo?
