New little girl...despite being only almost 3 has a SOLID neck, its really hard under her neck and she is all built wrong, she is a nervy little girl and is a touch overweight at the moment (have to have a good feel for her ribs ) What can I do to soften up the muscle under neck?? She is fed with her haylage net (with hay) hung low, turned out during the day. We have only had her a day but all our horses have nice correctly built necks and poor gal looks like a bull with her neck as it is
