Flying creatures, fly skill and entangled condition

[Cuttler]

If a flying creature becomes entangled, can it still use a normal move action to keep flying without having to roll for a Fly skill check?

For example, PC targets and hits a chimera with a rime cold spell (such as snowball. Chimera becomes entangled. On it's turn, the chimera now moves at half-speed.

I assume it can still use a move action to keep flying without having to roll a fly skill check. It could use that move action and move 25 feet (instead of regular 50 feet).

From the Flying maneuver table (CRB p.96):

Move less than half speed and remain flying: DC 10

Side question:
Is there any negative impact on a flying creature to become entangled other thant the condition itself??

thanks

As the Fly skill mentions, the skill check is only needed if the flying creature moves less than half their speed (though they can also attempt to hover at a higher check).

So in that regard, the answer is, "No, it does not need to roll a skill check if it still uses a normal move action (as long as it moves the full, halved speed due to being entangled).

As for the side question: There is not additional negative impact beyond what the entangled condition already creates.

Hope that helps.
