It could be RI a respiratory infection. Does she have any mucous around or in her mouth? wheezing zounds when breathing? puffy throat? My woma went off food one week, stopped flicking her tongue and when i had her looked at she had a massive case of R.I, that was treated but it was too late and she died. But they discovered she also had tumours in her mouth and was generally in poor health since birth. Im not saying this is whats going on with your BHP, but look into it more. do you have a reptile vet nearby?
