Can someone PLEASE answer my question! I asked if a 25 watt red bulb will work for two small chicks. Thanks for all the help, but I am not using an aquarium for the brooder. I am using a sterilite bin. :/
I used a 25 watts with an incubator and it provided a stable 100 decrees F.
How are we supposed to know enough about your set-up to answer that? If you take a thermometer and lay it in your brooder, you can answer that question quite well yourself, much better than we can. You can adjust the temperature by raising and lowering the heat source until you are happy with the results.
It does not matter that much how many chicks you have. What matters is, with your individual unique set-up, will that bulb keep one small area of your brooder warm. In a protected area with fairly stable temperatures, it should certainly be possible if you get it positioned right. If your brooder is in an area with widely fluctuating temperatures and maybe subject to breezes, it may be more difficult to get it stable.
