will this brooder work ? it is a dog kennel turned brooder. i just put cardboard on the sides, it is approx. 2' x 3'. i am wondering if the lamp will heat to a sufficient temp on top ? or will i have to put it on the sides ? it is a 250 watt red lamp. Should work eh ? My chicks come in 10 days, so i hope so..... i will be getting 9 chicks...... our lil girl is getting excited to have them !
