It has an automatic egg-turning function. It turns the eggs automatically, so you don't have to manually turn them. The incubator has been cleaned and disinfected after one use. Although it's made overseas, it works without any problems and operates normally within the set temperature range. A USB charging cable is included, and it's convenient as you can easily use it by plugging it into your home USB charging adapter. The baby bird rearing set has never been used. Unfortunately, no chicks hatched, so I will give it to someone who needs it.
