Cold horse, would else could cause?

[ahlam1399]

My mare is 16 yrs old this year. Out of work since Nov due to my pregnancy. Full turnout since yard move in April 17. Usually a good doer and struggled to keep her down in the summer. Welsh cob x Hackney worming in date.Last month or so she dropped off a lot so added coolstance copra to her feed- which helped. Shes currently on hi fi mollasses free half a stubbs, fast fibre 1/3 stubb, coolstance copra 1 coffee mug and turmeric. Shes had ab lib haylage since december. When she first dropped off I added the copra and upped her rug.Last week the grooms felt she was cold so we put her HW and MW on. Asked them to leave just her HW on yesterday. But she still felt cold and although covered still a bit ribby for her so we have kept both on for now. Chriopractor this week anyway Dentist this week anyway Am I missing something obvious??
