Can anyone tell me if I'll need my heat lamp at all during the day? Is there a guideline for outside temps and heat lamps? It's roughly 80 to 90 outside during the day 70s at night. These will be new chicks. Only 2 in my coop covered in mesh so the big chickens leave them be
Here's your guide: Given that a baby chick has a body temp on either side of 100F, if the ambient temp is close to that, meaning from 90F to 100F (first week), the chick will lose no body heat, therefore no additional heat is required. (Heat needs decrease as chicks grow in feathers until they need little or no additional heat by age four weeks, regardless.)
I've found that chicks are actually comfortable down to 80F during the first week without additional heat. And they will even find 70F not a problem for extended periods if they can warm up occasionally.
So, the farther away from the natural body temp of a chick the surrounding temperature is, the more likely the chick will need a heat source to warm themselves. The closer the surrounding temp is, the less likely the chick will need a heat source other than the natural environment. Note of caution: beware of wind chill and avoid cool drafts which can suck heat from a chick's body regardless of temp.
