my friend has 6 horses in total and has been introducing the filly to the other girls gradually as when they first went in together they used to pick on her. The other girls leave out atm and the filly normally goes in a paddock next to them for a few hours everyday so that they get used to eachother. my other concern is that the filly was a 'dummy foal' and even though she is much improved to what she was she sometimes doesnt seem 'quite right'. she seems happy in herself and loves her food but sometimes she doesnt seem to be all there. she will walk round her stable in a daze and is unsteady on her feet. (vet has been out to her and all is fine he says) i wonder if she has suffered any sort of mental damage which is why shes acting the way she is and why she reacts so violently to people she doesnt know??
