Assembled bird eggs are replaced by wooden mulches for a variety of reasons. Some pairs of birds are so careful that they do not share eggs with each other during the transition period, steal material from “neighbors” for the nest, and constantly roam.
Often during such a fight, the eggs are broken or thrown out of the nest. The eggs that fall from the nest get cold and the chicks they contain die. If the shell breaks during a fight, it opens the way for the spread of various environmental diseases.
When they notice such behavior from the birds, the keepers unexpectedly replace the fertilized eggs with wooden mules until the parents caring for them explain the relationship with or among the neighbors. Other birds do not care about their laid eggs due to lack of experience, sensitivity to disturbances, or lack of parental instincts. The developing eggs are then placed in a hatching incubator until they begin to hatch.
The extracted eggs are disinfected, weighed and placed in pre-prepared incubators. They ensure optimum temperature and humidity at all times depending on the species of bird, and are used periodically.
The eggs are used to prevent the inner embryo from adhering to the inner shell membrane. If the embryo touches the membranes of the shell, it attaches itself to the shell and dies. After 5-7 days of incubation, the eggs are ovoscope, illuminated with a special device, an ovoscope.
If the egg is fertilized, the blood vessels are visible. The specialists regularly weigh the egg to ensure that the birds develop normally in them. Interestingly, a normally developing egg becomes lighter over time. This is because the egg loses the necessary moisture through the shell and the shell membrane. The egg must lose at least 10 percent. your starting weight.
The eggs that hatch from the egg are returned to the leeks again, or the adoptive parents generally continue to be successfully raised. Only in rare cases, when the birds no longer accept their young, are they artificially raised by keepers. Large aphids, pink pelicans, white-fronted game and other wings were artificially cultivated at the Lithuanian zoo.
On public holidays, the Lithuanian Zoo will be open at regular hours, from 09:00 to 18:00. (departure until 5 pm). Starting April 1, the indoor exhibition (terrarium, tropical bird house and aquarium) at the zoo will be open for one more hour, from 09:30 to 17:30. (On Mondays, the terrarium opens from 12:00).
Visitors can view the giraffe indoors or in the outdoor aviary on warm days every day from 2:00 PM to 4:00 PM. Our goal is to ensure that a visit to the zoo is not only fun for everyone, but also safe, so visitors can only enter the indoor area wearing protective masks. The number of visitors admitted to internal exhibitions at the same time is also limited.
