Mating and Egg Laying
Grass snakes generally mate in the spring, shortly after emerging from hibernation. Males will compete for the attention of females, engaging in a ritual combat to determine the dominant male. Once the female has chosen a mate, she will lay her eggs in a warm, sheltered area, such as a compost heap or a pile of rotting vegetation. The female will typically lay between 10 and 40 eggs, which will hatch after approximately 10 weeks.
Growth and Independence
After hatching, the young grass snakes will be around 20-25 centimeters in length. They will feed primarily on tadpoles and small fish, although they will also eat insects and other small invertebrates. As they grow, they will gradually begin to feed on larger prey, such as the common frog. After around 2-3 months, the young snakes will become independent and will begin to explore their surroundings on their own.
