We've been doing our research but thought some input would also be nice from here. We are getting 1 day old baby Rhode island reds today. We only have a 175w bulb but the chicks will be in our home in a 2'x4' box. Will this be warm enough for such young chicks without any issues? We know to look for huddling under lamp etc but wondered the general thought on not using a 250 w bulb, which seems to be most commonly recommended?
