Forgive me if this has been covered already. Please point me to the thread if it has. I have a mixed batch of chicks 4 weeks and 2 weeks old. They spent their first two weeks in a brooder going from 95 to 90 degrees. Now I have them in the tractor and have been only letting them out into the run when temps have reached 80. Whenever they are in the coop, I am sure to keep the temp at eighty or better for now and I plan to go down 5 degrees next week. Right now we are obsessing over the temp. We've even installed a remote thermometer, so we can monitor the temp in the coop at night. The chicks are not huddling or panting and can be fournd scattered about the coop from the corners to the highest roost, to splayed out in the bedding at any given time. We are having standard issue fall weather with highs in the 80s and lows in the upper high 40s to low 50s in the evenings. Will I reach a point where these chicks will no longer need the heat lamps? What would that age/outside temperature be? Is it ok to leave them out in the run on cooler days if I move a heat lamp out to the run? They really hate being confined to the coop, now that they have had a taste of the run. Thanks in advance for your help.
