I’ve noticed that as well. That’s definitely not a far-fetched idea since Samson arrived in spring 2018 and both him and Rose are proven breeding animals. Since she has visible mammary glands, there’s a good chance she is pregnant since Lily passed away nearly 3 years ago and there are no other calves within the herd meaning no calf would have suckled from her in a pretty long time.I don’t know if anyone else has reported this already, but I’ve recently seen some pictures of Rose-tu at the Oregon zoo and she looks quite rotund, with semi-noticeable mammary glands (especially compared to Chendra and Shine). Is it a far-fetched idea that maybe Samson and Rose-tu successfully mated and there is a calf on the way?
