June and July are the months of the truth for a grouse breeder. Egg laying starts at the end of April, and incubation is done in the month of May. Most of the grouse eggs are incubated using artificial incubators (Grumbac) with authomatic control of temperature, humidity and turning of the eggs.
The most happy moments for a breeder are on the day when the youngsters are hatching and being transferred from the hatcher to their first nursery box where they are given sufficient artificial heat to survive for the first week. Already at this stage, young plants are collected and cut, and fed to the chicks to familiarise the chicks with their normal diet.
