Almost a week old, its hot here, can I get rid of the brooder light?

I was recently in the same position with three banty chicks (I now have them outside at a little under 3 weeks old and they're doing fine) I did keep the light on them at night while in the house to keep temp at 80 from end of first week, placed them in natural light with an area of shade to hide in if too hot. I figured there were three of them to stay warm, they huddled but didn't smother. So I guess it depends on how many goslings you have. Can they keep each other warm? Do they have a warmer spot to go to at night? I covered part of pen with blanket at night for the first 3 nights outside? Does this help?

 

My ducks huddled so quickly and I took the light away within a week in my house. I put them outside at 3 weeks and they did just fine in 30 degree KS weather. They are hardier than we give them credit for!
