Does anyone have experience with Quaker parrot with fatty liver? Mine I fear are displaying symptoms of it due to a diet of nutriberries and perhaps not enough activity. I know now that I will have to make changes to their diet. However after researching health supplements, I see two options to detoxify them. One of them is Avitech Milk Thistle / Dandelion Root - Liver Detox and the other is Lily of the Desert Aloe Vera Detox. Could please guide me and tell me which of the two is better(effective/safe to use) or if theycan be used together, alternately? thank you
