It really sounds like she's getting close. But only time will tell.When i push down on those sides it feels squishy, i wiggled her tail and it feels kinda loose, but she tenses up too whenever i touch her tail.
I looked for more discharge i dont see any more. Shes just walking around eating. Shes been shoving her head into the hay. Which she never would do before. Then just go back to her pen nd ly down for a couple hours then walk around and eat again.
Its not uncommon for one to want to snack off and on while in labour. It wont hurt her and will give her energy when it gets close to delivery.
Make sure she drinks water periodically but don't leave a bucket of water in the stall where she can back up to and deliver a kid.
When you see an amber colored discharge, birth is immanent. But it could happen anytime or not for a few days even a wk. Be paitent.. it'll happen.
Best of luck! Im excited for you.
