table was super donkey with lots of small raise (like preflop here) and many donkbets. especially CO did donkbet/stabbed a lot of flops
MP (Openraiser): 46/28, was minraising every hand, he decided to open
CO: 84/40 over small sample
EP: 34/12 (dont have any reads)

Is it a mistake to not 3bet here, if you anticipate you will be OOP against minimum 3 players? I know this hand is super premium, but my experience in those kind of situations is, that i do not have a profitable spot, because i always have to c/f unimproved or even have to fold on later streets. It is because of the SPR of about 3-5 which i dont like.

I could have led the flop here, but against FIVE players i think i will often just get raised by ATxx, the others will fold (which is a shame) and have to stack off flipping. Also because i knew CO was stabbing a lot i checked.

Option to c/r here. Although i dont think CO has ATxx all that often here, i dont think i should raise here. Wanna keep them all in the hand.

Planning on c/c against CO, but suddenly UTG throws in a bet. CO calls, i call (again, dont see a reason to raise here)

ding, ding, ding! Here is why iam mostly posting the hand. Do you think its a mistake to check here against these donkey players, that proved to throw in random bets all the time? I found it very reasonable UTG checks and CO takes the betting lead again repping exactly a hand like mine (which would be believable imo). I think both of them thought i was super weak and no threat.
Should i just donkbet here? If so, how large?
