Measures
(a) Check the mating conditions accord-
ing to the recommendations of the
breeder.
(b) Feed the roosters separately, so that
the chickens do not take most of the food.
(c) Do not use too many male animals;
keep the breeding roosters together; build
a non-permanent solid separation walls
between the individual breeding coop or
separate them within bigger breeding
coops
(d) Ensure that their coop is comfortable
and there is enough suitable drinking wa-
ter.
(e) A young rooster is required
(f) An unsterilised rooster is required
(g) Do not keep the eggs for more than
ten to twelve days; store them at a cool
temperature (8–15
midity of 75–80 %. Turn the eggs at least
once a day around their longitudinal axis
(a) Check the thermometers, thermostat
and the electricity, follow the instructions
of the manufacturer
(b) See 1 (g)
(a) See 2 (a)
(b) Turn the eggs frequently, at least 4–5
times a day; always turn them into the op-
posite direction
(c) Check the feeding
(d) Increase the air flow by normal means
(e) Only use eggs from healthy stock;
check the hygiene measures
(a) Increase the evaporation surface with
water or sprays
(b) Check the humidity temperature
measurements
(c) Check the food
(a) (b) (c) Adjust the temperature regula-
tion accordingly/ adjust it properly
(a) See 2 (a)
(b) See 2 (a)
(c) See 3 (b); ensure to insert the eggs
with the wider part first
Use wire inlay or cover the slippery/
smooth ground with e. g. sackcloth
