Thank you for your reply.
She is eating a lot of hay. I have 3 kinds of hay from Vitakraft VitaVerde: the one with dandelion, the one with wild rose and the alpine meadow hay.
I give her some of these but for regular ones:
I give her 1-2 drops a day(not only this flavor):
Other mixed pallets that i don't remember the producers name.
A couple of dried fruits from Padovan once a week:
Once a week some Herbal Treats from Padovan(the ones with malva and mint)
And some dry bread from time to time.
Veggies and fruits i stoped giving them to her because i thought that could be the problem, but they aren't. The same with the drops too. I don't give her carrots because she doesn't like them.
