Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earthâs surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals.This mineral composition usually gives granite a red, pink, gray or white color with dark mineral grains visible throughout the rock.Granite is the best-known igneous rock.ranite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals.

This is dry, air, almost absent of humidity. Each year we know that egg production will drastically decline and that a heat induced molt is coming. The molt is not really from the heat but from the stress it places on our flock, so technically it is a stress induced molt.
The comfortable temperature for optimum laying ranges from 18.3 to 21.5Â°C (65Â°-70Â°F). Both higher and lower temperature affect the egg production and quality of eggs adversely. Egg production starts declining when temperature rises more than 27Â°C while egg size starts reducing from temperature of 24.5Â°C onwards only.The higher temperature in general is more harmful to birds than lower temperature.bout 12 to 15 cm linear feeder space and 2.5 cm water space per bird is adequate during laying. On deep-litter system one laying nest for every 4 to 5 hens with perch at entrance is provided for comfortable laying and clean egg production.
