The party has an Alchemist. Who WILL be flying about raining bombs, which is pretty dang cool. So the enemy will be summoning 1d4+1 Eagles (twice) to attack him.
Are there official rules that govern distraction / concentration in an event like this where he will need to mix his bomb and use it the same round he is being dived into, pecked and clawed by multiple opponents?

Nope. Only spellcasting requires so much concentration that getting attacked may screw it up. IIRC, the only thing bomb mixing and throwing would do is provoke an AoO. The birds could disarm the alchemist then, I guess, although that is probably too smart for a pack of birds. The summoner could have a spell up to talk to the birds and direct them?

Wouldn't disarming him possibly drop a live bomb?
