Hi,
Also, if you are using a 250 red heat bulb, turn it off. The 250 reds are a heat lamp bulb. Their purpose is to heat objects in their realm of effect. This is why we see so many chicks get overheated each season when these 250 red bulbs are used. The 250's also tend to dry out the brooder faster which causes the humidity to plunge and the chicks to get thirstier .The incandescent bulbs cast heat as a side effect of their being on and anything in that realm of influence can take advantage of that heat. Use a 60 to 80 watt incandescent bulb. Not an LED bulb. Make sure the bulb is not Teflon-coated. It will say on the package. Teflon-coated bulbs give off carbon monoxide as a side effect and it will kill any age poultry. I read of one lady who put one of the Teflon bulbs in her coop and the next morning all 14 of her chickens were dead. Usually these bulbs as listed as "rugged" or "outdoor" bulbs.
Put your incandescent bulb on a chain which can be raise or lowered according to the chicks needs.
The chicks will tell you what they want.
1. If they are crowded under the light, they are cool and the light needs to be lowered.
2. If they are escaping the light and you find them in cooler corners, raise the light, they are too hot.
3. If they are loosely gathered under the light and calm, the temp is just right.
Best,
Karen
P.S. Also check them for pasty butt. If there is a plug of dried poop over their anus, you need to gently massage it off with a soft wet paper towel soaked in warm water. This plug will keep them from pooping and eventually kill them.
If you get the heat right, the Nutri-Drench should help keep the pasty butt from re-forming.
