To answer this Task….“Knock out 5 opponent birds with rage attack”: Note that this does not have to be done all in one battle. If you win the battle, the number of birds you KO’ed using the Rage Attack are incremented accordingly.

I would like to Thank @KillerKea for your help. I followed it and I used Bomb(Captain Class), Blues (Skulkers Class) and I changed here and used Red (Paladin Class) instead of Chuck and I also used The Golden Rage Chilli. Here is how I managed to win this Daily Objective.
I used the Captain Bomb’s Whip On as advised, Then Skulker Blue to hit The strongest of the opponents Birds because it leaves a weak spot. Then I Used Red Paladin to hit the second strongest bird and As you recommend using Captain Bomb’s explode on the now weaken opponent’s Birds…I used the Golden Rage Chilli on Bomb, I made him explode and since all the enemy birds’ health were low enough the Enhanced Explode Knocked Out all 3 birds. I kept repeating the same game play plan for 10 more battles with the same result…WIN.
