Mine are all out. I have four out on the hill, they have hundreds of acres to roam, and are grand. I then have three in one field with ad lib hay, eating about a bale every 5 days - one 20 year old highland who is fully clipped and wearing a heavy weight full neck rug, one eight year old highland mare who is looking leanish and very muddy and bedraggled, but just right in preparation for spring grass, plus she is going to be backed this spring, so that will be much easier for her if she isn't heavy, and one eleven year old shetland who is blanket clipped with no rug. I did this in the Christmas hols as I was worried that he wasn't losing any weight. His enormous heavy mane lies both sides so keeps him dry, but he is slowly losing a bit of podge. I felt a bit mean doing this, but decided it was better than getting laminitis later in the year, or separating him from his friends. He also wears a dinky ponies grazing muzzle - he can eat the hay through this, but not as much as he would otherwise. Then I have a group of four highland fillies aged rising one to rising four in another field by the house with ad lib hay, eating about a bale a week. I just went out to check them this morning and they were so wet and miserable I have brought them inside. I know native ponies are designed to be hardy, but not to be soaked all the time. In general I am not a fan of rugging natives with their full coats on, it can often do more harm than good, but two of them won't be going back out until I have rugs to fit them - I only have one for the shettie when he is fully clipped, and big ones for adult highlands, so going to have to spend some money today. To be fair, the other two were completely fine, but they are a bit of a team and would have just shouted for each other all day.
Its pretty hard to judge from a photo, but I would say your ponies look pretty much like everyone elses do in this poxy weather.
