How to unlock the Careful steps achievement in RiME - Definitive Guide
Take care not to step on any seagull nests on the way up, and the achievement will pop when you reach the sphere.
Go up the staircase which has large, blue orbs on the archways. I think the fox leads you that way already.
Solve puzzles to raise a tower that you then have to climb. Avoid stepping/running/jumping onto any seagull nests that you see. I know there were at least two nests, one before and one after jumping off the tower, but there may have been a third.
Throughout the first chapter, you will find the skies and often some of the terrain are littered by seagulls. Furthermore, there will also be some nests near your traveled paths. To obtain this trophy, simply do not walk/run into any of the nests, preserving the seagulls and their offspring. You should obtain this trophy once you've scaled the large tower to send your shout and awaken the three orbs (thus watering the great tree below).
If you obtain this trophy at a different point of the chapter, let me know so I can try to narrow down the specifics and hone the solution for later players of the game.
During Chapter 1, you are climbing a tower via a central pillar to activate a larger blue sphere. On the way you will go past some seagull nests full of eggs. Get to the top without breaking any of the eggs.
Stage 1: Denial
During the area where the sphinx is, one of the keys will require you to fill the area around the tree with water. The path that you need to take in order to make this happen is filled with bird nests that have eggs in them. You will need to avoid the nests while going towards the top of this area, so make sure you watch the ground carefully because you may accidentally walk or jump onto nests and break the eggs (which will negate this trophy). Once you get to the top of this area, right before you scream into the giant orb, the trophy should pop.

After that, dive into the water under the tree and get another trophy.
