A texture pack that adds different chicken breeds in your game! You will need MC Patcher http://www.minecraftforum.net/topic/1496369-143-142-132-etcupdate-1029-mcpatcher-hd-fix-243-03/ for this to work. With MC Patcher patch your game with the "random mobs" option. It so far only has 5 other chickens, but there is lots more to come!

Chicken 1: Default Minecraft Chicken
Chicken 2: Black Austorlop Chicken
Chicken 3: Golden Sebright Chicken
Chicken 4: Rhode Island Red Chicken
Chicken 5: Aseel Chicken
Chicken 6: Java (Molted) Chicken
