Day-old chicks do not need their humidity to be monitored.
Chickens typically live in a coop or hen house on a farm or backyard setting, where they are provided with shelter, food, and protection from predators. They roam freely during the day and return to roost at night.
You can keep "chicken feed" available to them 24/7 byrumjr I feed my chicken two time each day. Chickens should eat all there food within one hour if not rats will come after some time.

"how much does humidity change in a day?"
Humidity is dampness in the air. The intrument that measures it is a hygrometer, and a day with low humidity is more comfortable because its easier to breath
Of course, purple chickens have special powers.
The average relative humidity on a rainy day would be closer to 100 percent humidity. Rain adds moisture to the air, increasing the humidity levels to near saturation point. This leads to a higher average relative humidity compared to a non-rainy day.
You need water to live, and for your body to function properly. Your kidneys help filter toxins, but they need water to work. Your blood's liquid part is called plasma which is water. Without blood you cannot survive. If you are a plant you need it to perform photosynthesis (the way a plant makes its food it requires water, oxygen, sunlight, soil, and free living space). If a plant can not do this it will surely die. We even eat plants to live. Cows and chickens eat plants, so if you like cows and chickens you can indirectly thank water for providing us life. Our bodies are made up of approximately 75 percent water. We can potentially live without food for some days but without water we would die. We need clean water for day to day life.
They usually live in what is called a chicken coop. Some are allowed to run free (free range) during the day but are shut up at night for their own safety.
The ideal temperature for hatching chickens or ducks in an incubator is between 99.5F and 100.5F. The temperature is not the only consideration as the humidity must be right also. Eggs should be at a 55% humidity rate through to the 18th day and raised to better than 65% during the final days.
You will need at least 15 chickens in prime laying condition and of a breed that lays daily. To ensure 15 eggs per day you would be best to have a flock of 20 hens, all between 8 and 18 months old. Check the related link below for breeds that produce up to one egg per day.
