The best chicken defense mod I've ever played is robot defense or tech annihilation chicken defense mod. The mod itlsef is basically BA but with more than the double number of units, a third faction (so core and arm aren't the only choices), t1.5, t2.5, more t3, t4. t3 ships and t2 hovers as well as spider factory and helicopters one, all that you don't have in BA.
The chicken mod is much harder than BA's. Chickens are units (tanks, bombers, etc.)
The queen on hardest settings has 24 millions HP and takes about 2 hours of in game time (so more like 3/4 hours or real time since you get 1 FPS at this point of the game). But the problem is that if you stuck her she won't kill you and you will eventually win withing hours so it's a really big problem.
That's why making the queen 10 times more HP than now seems a good idea rather than 100 times. And as I said, I'd love to see new chickens too.
They still continued the zero k chicken mod (the crimson's clan) but the interface is a very old CA's one so it's really hard to play. But there are much more interesting morphs and queen options, etc. I had tons of fun with it. Now it's unplayable due to the interface.
