Depends where you are and what the temp is where you are living after 2 weeks I had a set of 15 chicks sitting under their momma but the momma decided she didnt want them any more and stole some more eggs to sit on. They have been in my house now since they are going on 3 weeks old and I have not had them under a heat lamp at all. But mind you there are 15 of them and I am in Texas its pretty warm here. They have all been doing really good so far. If its cool where you are or even any drafts I wouldn't take away their heat lamp just yet. You need to weigh the pros an cons and see what is best for them.
The temp for your chicks should be 90 degrees.85 next week..80 the week after that..is the rule. Try a red heat lamp. It's not so bright.
Mine were the same way. I have a brooder which requires me reaching over them, which I think can make it worse. They just seem to get excited over any change. Mine got use to me, but now, at five weeks, they are getting a little excited and peeking at me (some of them) which I hear is normal.
It's normal for some of them to be afraid. Just try not to startle them or reach down at them suddenly. Talk to them to get their attention before "attacking" with the BIG hand. Some will love the attention and others not so much.
If I were you, I would put a thermometer in your room and try to see what the temp is like when the room is the coldest at night, and as 'Birde' explained the temperature rule, go off of that to make sure your chicks are receiving the best care. Or you could try to hang a sheet to try and block the light? Just don't drape it over the brooding lamp.. that could be a bad idea.. lol
