Had a birdstrike (we think) break the starboard side window at night last year in an RA390 coming out of Norway. Didn't notice it at first just heard a light thump at about 2000' but later on levelling at FL270 we noticed the outer glass layer was crazed. We carried on to destination pressurised and with the windshield heat on low, as normal. No problems and screen took the 7 diff OK. The engineers didn't want us to fly it back even unpressurised as they were afraid the glass may start to delaminate and go through the starboard engine which would get (even more) expensive.
It seems the other layers are mighty strong, even with the outer one broken.
If I knew how to attach a pic of it to this, I would ! Help? ...
