I was wanting some opinions on what's the best way to put weight back on birds after illnesses? I have been unfortunate enough to have two severe cases of wry neck this past month. Luckily with vitamin E and B Selenium and predinsone they have both recovered thank God !one is 100% the other is very very close to being 100%. The problem is the illnesses lasted around 3 weeks and both have lost weight. What would you suggest to help them gain there weight back? Thanks so much.
