The first time I got this idea was when I tried playing skirmish and accidentally chosen survival on a normal map, without noticing it. However, I tried continuing, and... It was fun. Unlike normal chicken maps, on non-chicken maps, you're actually rewarded for expansion, and I thought that this could be interesting. Second great improvement is that your flank placement is more uncertain. 'Should I place a defensive outpost on this entrance, or should I wait until I get an army and push my frontline further?'
It was loads of fun! However, I struggled to win the game so hard that I have asked for an advice.
Apparently, nimbuses, in large amounts, defeat chickens with no problems whatsoever.
Raiders early on keep the big chickens from coming.
Then, stardusts.
I've only seen one person beat suicidal chickens on a non-chicken map, and his name is [ffa].
