Update Shoshone & Henna:
I still have not seen any changes in Shoshone so I am now convinced that she was bred at a later date than we originally thought. Storm was the only stallion on the farm with her so we have no doubt about who the sire is...just the dates that are mixed up. I will continue to bring her in at night and put the foaling monitor on her because last year she did not have a bag before foaling and showed no real indications that she was close. No much I can do except wait and see when she foals.
I have Henna in the stall next to Shoshone. She is a maiden mare and is starting to form a small bag. She is not due until May 24th. I have been bringing her in just so that she will get used to being in the foaling stall and she can also keep Shoshone company in the barn at night. I will not be putting a foaling monitor on Henna until I feel that she is much closer.
