So, today I brought in two males ferrets ( about 5 years old ) and I need some tips on what others have found to be the best to nurse back to health... 

A little back story: 
I got them from someone who took them out of the situation they were in ( her kids are allergic and can not keep ) 
for at least 6 months they were fed nothing but bird seed and ferret treats... 
one seems to be doing good... fatter than the other and eating. the other one is super skinny and walking funny ( thought to be due to weight and vet says to try and get him to eat and put on some weight and go from there) 


unsure of when the last time was that they ate any animal proteins, other than dry food and duk soup. 


I am seeking ways to get them to gain weight, eat right, and generally be happy and healthy for the rest of their lives. 


They are playful, excited, and so sweeet!!! 


also, when is the best time and what kinds of proteins should start being introduced? I do not want to rush it and make them sick. 


I don't even understand how someone could do something like this to an animal :(


TIA! 

Hello and Welcome to the forum!
I feed mine Dr Foster and Smith I buy online. I also feed them soupies 3 times a day. My soupy consists of kibble, water, eggs, Beechnut chicken baby food (1st stage) and to help add weight heavy whipping cream.  I also add some pure pumpkin to help with hairballs. I soak the kibble over night and blend everything in my food processor. I usually make it thicker because I can always thin it down. 
The one having trouble walking and is skinny. Have you had a blood glucose done? It could be from diet but also insulinoma. I would get it checked if you haven't. I have one with insulinoma.
Be sure and post pics of your little ones.

I would say sooner is better for a good diet.  Get them some decent cat food for now, if you can't get ferret food.  We feed Zepreem Drs Foster & Smith and Natural gold cat food.  You can get Zup and Nat Gold at some pet stores.  You can also try raw egg that's warmed to room temperature.  

Thanks for taking them in. Don't be afraind to ask questions.  We're here to help.
