Can't tell from the pic. Looks ribby and rafter hipped indicating needs weight/condition, possibly wormy, hair coat doesn't look great so again...... but would need more/better pics to actually be able to give a serious condition appraisal/BCS score.
GH to be fair, I'd say not too bad. Fluffy winter coat which is good as horse appears to be living out, though dull. Maybe give access to a mineral lick in case anything is lacking.
Second picture looks like a healthier horse, but that may be due to the flash. You can take pictures at different angles, different lighting and it looks like could be two different horses, could be the same one.
I'd just make sure worms are clear, espcially if horse's sharing a paddock, mineral lick and possible feed up.
Also, the top one doesn't look ribby ribby, may be a bit on the slender side, however any ribby look appears to be higher than where I would expect it to be.
My first thought was haflinger..I see a belly, fatty withers and butt which indicates overweight, but if it is a haffy I would consider this fairly normal lol. Its hard to tell with the hair, but looks like some ribs?? If so I would reccomend worming. But otherwise looks heathly and has his winter woolies.
Ok after I saw the second pic, defintely haflinger lol. Lovely shine and glean to a woolie winter coat. I would say looks pretty good :) Haffys are just a little chunky already, but a good weight for winter.
With that last pict I'd say a 5. Maybe preggers with the dipping withers??
Shoulder & neck looks fleshy and muscled. Still can't tell...
Dying to see the whole picture! Coat looks nice in this one, not dull even for a winter coat.
