I think this is what I was hoping you would say and is also the advice I have received from someone elsewhere. I needed to know that it was ok to give her the benefit of the doubt for a while, which I know sounds a bit ridiculous, but I couldn't bear the thought of her suffering. I have ordered some Emerald which is meant to be very good as an intensely nutritious feed to keep her strong. I have ordered a worm test kit to see if she's clear in that respect. I do sometimes think she has a little bit of sight. I will continue and will keep in touch. Thanks ☺
