Checked it out, and I won by killing all my enemies chickens.
Would be nice if you could sell your feeder and coop in case you regret, or as a strategic move.
Also, in case you aim to further expand this game it would be nice to have other objectives than beating your competitor, as the game will only last as long as the AI does (or you of course). I.e. I won at day 12, and as a result I didn't get to delve into the more complex strategies of coops, ponds, and venturing out into the forest.
