great news thats she is going to be ok ,a few years back i picked up a jill with a womb infection she needed to be speyed quick she lost all her fur totally bald for a few weeks and then it grew back ,bald adult ferrets are as ugly as baby pigeons ive got no picture of her i wished i had took one ,it was the sudden change of hormones what sent her bald so dont worry if the same happens to your little jill
