The one thing you dont want t do is cook the babies!!! if you keeps the light on when they are at least 5 weeks old in the middle of the hot day that could make them to hot. Oh and by the way to any one whos reading this, did you know that chickens pant! Just like dogs do huh huh huh huh!!! that how it goes. By the way i am am 12 years old. A first time chicken farmer! No pun intended!
Welcome to the forum. Looks like you are already learning alot about your birds. Keep it up and you'll have tons of happy little chickies before you know it... of course if your parents don't stop you!
I'm new to raising baby chicks and had been working on temperature control in an outdoor brooder I set up in our coop right after I ordered my Banty babies in February. They weren't due to arrive until this month but I wanted to be prepared. Had it just right for the colder than normal winter we had in TN this year. Sooo, a week before they were due to arrive I did another "test run" and we've been close to 90's for most of our supposed Spring season. You can just imagine my horror stricken face when I checked the outdoor brooder temp the first morning of the new test run...it was 120 degrees F. I cried at the thought of "what if the babies had been in there?" So I changed things up and they are happily residing in a brooder cage in one of our spare bedrooms.
The one thing you wanna be able to do when brooding, is adjust the height of the brooding light. If it's either chained up, or on an arm, then that shouldn't be a problem. The higher the light, the lower the temp. The brooder temps needs to be dropped by 5ºF approximately every 7 days.. Just a thought.....
