No I haven't tried playing. She and her pasture mates keep walking away. I'm going to let them get situated with their new surroundings. I guess. :(
And they somehow managed to pull the hook out of the gate so now they're outside the fence... and I have tried everything to put them back in :X though I don't think they'll go anywhere cause their mom didnt get out. Im assuming they'll stay near her as long as theres water and plenty of grass around.
If there is one horse left in the 'right' field can you catch this one? If so, put a halter on her and bring her in/tie her up/ somehow contain her within sight of the other two. Then open the gate so the two miscreants can get back in. Then makes sure you do NOT place yourself between the gate and the escapees - you don't want to inadvertently stop them returning.
If they don't show any signs of going in you may need to herd them in.
It sounds like you need help on the ground with these three; there's a limit what people on the internet can do!
