Bad turn call?

[Farfenugen]

Very loose B&M 3/6 table

I get 77 on the button. There are six limpers. I call.

Flop: K-K-5

Checked to me. I bet. Two callers, 3rd seat and 7th.

Turn: 6

Checked to me. I bet. 3rd seat raises. 7th seat folds. I call.

River: 2

3rd checks. I check.


Should I have called the turn raise?

Was I incorrect in thinking my hand was good on the flop against eight players? Should I have checked?
