I cannot tell you how much I recommend the ceramic heat emitters that are used for reptiles.
First, they aren't 250 watts and I don't think most of use really need that much heat. We had a brooder fire about a month ago and lost 2 chicks. It was caused by one of the red 250watt bulbs that came apart where the glass inserts into the metal. The hot bulb fell into the plastic brooder and caught it on fire. It was a miracle that the house didn't go up in flames as well.
Second, I have been able to get chicks on a day/night sleep cycle using the ceramic heat emitters. For the first week, I leave a lamp on in the room so they can see, but it's not shining directly on them. After they are up and around after the first week, I change the lamp bulb to a 15watt bulb so there is just enough light to dimly light the room. Around 10:00 at night, I go in, turn on the 15watt bulb, turn off the main lamp and tell them goodnight. They all settle right down into a big silkie pile and do not get up until the next morning. I know this because I have tiptoed in during the night a few times to check and they are sleeping soundly.
In the morning at 6:00 a.m. I turn on the main lamp and tell them good morning. They jump up, stretch their legs and wings and start running around peeping while I put in fresh water and feed. They play and rest all day and we repeat the cycle that night.
I will tell you that these are the sweetest and quietest chicks I've ever raised. I would never do it any other way now....
