My gelding has been getting kinda mean to my old mare lately since the weather changed and we haven't gotten him out. Yesterday I noticed him getting more mean then usual and just "herding" her from one pen to another ( I have 2 stalls that are open to each other I had a pig panel gate up but he ran through it about a little under 2 month ago and cut himself up so I just took it down) Anyways my neighbor shows up tonight about 9:30 and says she heard a loud bang and looked out and saw him just straight kick her hard, so hard she broke off the top wood rail. Anyways so my daughter went and got her out and she had nicks and scratches all over and then a large stream of blood coming down her back legs and tail. I couldn't see from where it was coming so we took off her blanket got some warm water and started wiping. I thought it had to be a decent size gash but found nothing,the blood was from her vagina down to her hooves. Anyways it was enough blood to cover that area but I was also thinking that it looked like WAY more then it was cause it is VERY cold here and I think froze quickly to her, so she's all cleaned up, we went and hammered boards up to separate them till I get a new gate tomorrow. Then checked her again and it seems to be coming from her vagina just a very very very small bit. So do you think that maybe she just cut herself when he kicked her or hit the fence or could it be something worse? No vet as it is x-mas none tomorrow either. She is eating/drinking normal we gave her some senior feed and some warm water,just seemed to be happy to be away from him. What do you all think? Should I be worried?
