Can a thin forelock be a sign of a deficiency in their diet? All of my horses forelocks seem to have thinned out over time. Other than that, they are in good condition.
They are on a regular worming schedule and are stabled every night with turnout all day. I have recently switched from a salt block in the pasture to loose trace minerals designed to supplement my area/local grasses. I top dress their grain with it to make sure their getting their minerals! They get oats with handful of corn and cocosoya oil every night and free choice of hay in the barn and pasture. They are sleek and shiny in the summer but now have their long, winter coats but their forelocks haven't thickened any.
I probably just worry too much but thought I would ask!
