I am just curious as to who follows the guide of brooding chicks by lowering the temp 5 degrees every week? In previous batches I have started birds indoors with brooders and lights and followed the temp requirements as they call it. Well this time I got a batch of 20 cornish x rocks and 10 leghorns. i started them in an old coop with open windows a hardware cloth door and a 60 watt bulb. After about a week i could tell the difference between the two breeds so i split them up. Leghorns in a small A-frame tractor and cornish in a larger tractor. The temps are about mid 60's at night and mid 70's during the day here so I gave both tractors a lamp after a few days I could tell the chicks didnt really use the light so in both tractors I took them out. Now remember they are 1.5 weeks old still mostly fluff. Its 60's at night. They are completly fine and happy. We must really baby our chicks. They are a lot tougher than wee think.
