Whenever I go against Chickens in BH, I just try to farm them down with the bow. I've never noticed myself getting really mad at a chicken. The thing I struggle with the most is definitely the flower pots lol x_x
Chickens are not good my personal favorite block to disguise as is the flower pot as it is very good and has a very very small hitbox you cant hit it I swear you cant hit it my favorite spot to use is a flower pot in water cauldron it is very difficult to see many experienced players like @Bobert2O13 and @NathanDoesMC would agree it is pretty difficult to hit them almost impossible. I feel like the flower pot strategy works really well on maps like The Museum and thames Square so I would vote those every time you see them.
chickens have the advantage of having smaller hitbox (while using sword) which makes them OP. also since they are so low you (the hunter) have to look down, which is further than looking straight. Plus the fact that I have 200 ping. In short, I hate them.
