Mare with foal at foot

'Izzie' 13h 10year old super heavy chestnut mare with coloured (3colours) colt foal at foot. Mare broken for ride and drive we used her on lead rein a few times before realising she was in foal so i can' t speak to her abilities but nothing seems to faze her. Foal Born 10th May mare is not covered again but will be if still here after her next season but will reflect in 💶. Bog burnt after winter lives out and foaled herself in field, great mum. No idea of foals sire but he is shooting up so I think he will certainly match her in height or bigger we haven't handled him much as she has been quite protective but seems to be settling a bit. Her breeding is not recorded but we are getting her sorted for a passport at present. Only up here as we are short on grazing and need field for pony for kids to learn to ride, may consider a swap for lead rein/first pony
