On the first to start it all a character tending 4 coops. Now have tamer tending 6 coops filled with battle chickens (tend to get more eggs from them). I have two lime green BC eggs to pop and then kill off the two lowest HP Battle chickens. They will need to beat 142 HP to remain alive. Once you start hatching BC you can get a fair ideal how many never made it off the small Tuko Isle I hatch them on.
Fav color one by far is the paragon gold one. Close second is the pink, not agi, color one with 172 HP. Have 3 black so far. Had a forth but it was a sickly 92 HP.
Took a bonded 5 out and killed discorded vopral bunny. Starting fresh they cap at 15 damage each. Not like a packy bonus make much dif with their 7-9 damage. Guess the 25% bonus each for 19 cap damage would unbalance the game.
