An alpacas baby is called a Cria which is the Spnish for baby. The gestation period of a cria is 11.5 months or 345 days. Both of our alpacas are expecting and the furthest along, Apollo, is 328 along. Birthing is generally carried out by themselves and has been known to be up to four weeks late. However, looking at our ladies, there is some serious movement in the tummy area and it seems that their crias are extremely active and may want to get out as soon as possible.
I'll update you further as the pregnancy progresses.
