I have three female chins (no males) and I am curious about what to look for behavior-wise during estrus. For about two days, Carmen seemed tired and cranky, and she also spent a lot of time licking at her genitals. This morning, she was back to her old, happy, bouncy self. I was wondering if this is typical behavior during estrus. She never stopped eating, and since she is fine today I'm pretty sure it's not illness. I'm open to any suggestions/opinions though!
