This is my first batch of chicks (arrived on June 9th, so thinking they are about 1 1/2 wks old) and I have a question about lighting. We have 20 chicks and currently have a 250 w. red light that allows us to keep the brooder at 90. The brooder is housed in our basement and the lighting in that room is fluorescent. We keep this on during the day and I am not sure if it should be kept on at night also or switch to a regular 70 w floor lamp or turned off completely. Thanks for any advice given..
