The only pros of not blanketing her that I can think of are that she could possibly shed faster and that she might be getting too warm under there right now (she's not sweaty at all when I take the blanket off, it's just warm under there and with it being consistently in the 50's to 60's lately...).
However, the negatives are that she's rather skinny right now and while I'm trying to get more food into her there's only so much I can do without going out there everyday which I just can't do, therefore she doesn't have much fat to keep her warm. I've been feeding her 2 little scoops (the scoop that comes with it) of Cool Calories each time I go out but that's only three/four times a week so so far it hasn't made a huge difference in her body mass. Another negative is that her field has not shelter so there isn't any way for her to get out of the rain if it starts raining, and then with her current skinniness, I really do not want her standing in the rain, cold and soaked through...
I would just get her a turnout sheet but I don't have the money right now. However, that is on my list for as soon as I get money. I have a little old lady that I do chores for and make $30 per time, but she doesn't want me to come unless it's sunny so I haven't gotten to yet. But that first $90 that I make is going to buy Miss Lacey a turnout sheet, no doubt.
So basically, what makes you say "it's time to stop blanketing the horses"? How do you decide?
If it were you, would you take Lacey's blanket off and leave it off?
