They ABSOLUTELY do NOT need those ambient temperatures 24x7. Sad "old wives tale" that many believe, including me when I got my first chicks. I followed those temps in a bathroom until they were close to a month old. WAY TOO HOT IN THAT BATHROOM. Every batch since then has gone out to the barn with the Mama Heating Pad brooder or a broody hen at a couple of days old. Zorra did a great job raising 3 batches with help from Anais. Anais shepherded the other batch, Zorra wasn't broody at the right time.chicks need
95-100 degrees week 1
90- 95 week 2
80-90 week 3....this is all day and night.
What they do NEED is the ability to go into a warm environment when they get cold.
These one week old chicks are in the barn in the brooder area of the coop with their MHP, May 1, 2018. At that time of year the lows would be 50°F or less, highs very unlikely to approach 70°F. They slept in the "cave" at night but came and went as they pleased during the day.
And do you think the hen with these 1 week old chicks is providing ambient temps per the "required" values in a drafty old barn? June 16, 2015. That door goes into the brooder area of the coop from the barn alley.
Out in the alley on June 20 with Zorra (Black) and Anais
