Is it too late to socialize my chicks?

We played with them a lot in their first week and got them comfortable with being picked up and eating out of our hand.

We left town for a week and had a friend watching them but they didn’t really interact much. We got home and they are terrified of us. They will be 2 weeks old tomorrow.

We feel like they get so stressed and overwhelmed when we try to pick them up or even put our hand in the brooder. They scream and panic. I feel horrible but want to try and resocialize them.

At what point in their growth is it too late to get a strong trust with them? I feel horrible scaring them and it makes me want to interact with them less.
