On the 10th of December a Balabac chevrotain (Tragulus nigricans) was born, the sex is currently unknown. Hopefully it is a male since there are only 2 males in Europa at the moment. Source: Instagram of Zoo Wroclaw (31/12/2022)
Yes, two males only. One in Wrocław (born in Chester) and one in Rotterdam (born in Wrocław). And eleven females. So fingers crossed that it's a boy.
