My mare gets equilibra and half a scoop of mix, with water added to make it a little mushy. She lives out 24/7 and gets this once a day. She looks really good on it.
She gets 500g of the balancer and 1/2 scoop of cool mix, to carry it as she doesn't like chaffs and the balancer pellets are very small. A bit of water binds the two together so the balancer doesn't drop out.
That's good, so if I introduced this to my 2 year old ID x she should be okay on it! Some people say don't give them anything, but just wanted make sure she is getting everything she needs whilst she is growing!
