My mare is in season at the mo, and has been in with mine and my friends horses for a couple of weeks, her and this one 'gelding' have been very close and stay together in the field a lot. I say 'gelding' as he acts very much like a rig and is always with the mares and really stands up to my gelding if he goes near any mare. My friend got a new pony (mare) and she is also in season and tonight me and my friend were filling up their water when we noticed this 'gelding' was mounting the new mare. When I say mounting he was 'in' and 'going for it'. He kept doing this whilst we were there and did it about 6 times in 20 mins.
About a week ago my friend told me that one of her mares had a white ish milk like substance dripping from her teats. I did not see this, but that's another clue. This mare is pretty 'fat' but she is one of those horses that lives off fresh air.
I'm wondering two things:
1) if the gelding is a rig can he get the mares pregnant?
2) if the mares are pregnant can they have terminations?
And 3) he should be pulled out of the paddock and kept on his own until a vet can check him over.
This is a potentially lethal situation, if he is mounting mares that often he could seriously damage them. If he is actually fertile and you have pregnant mares who have had no care then that could get ugly as well.
Please get someone to step in here, get the vet out, check that boy out, and get a lute shot for the mares.
Yep forgot to add mares have been took out and he is left in with the geldings, although the mares are all shouting for him :/ def going to get the vet tomorrow. Thanks for help! Mines only just come back into work after a foal she's not having another one!!! Thanks :)
