I've got 2 hens going through the molt from hell, they're thin and miserable in just about every imaginable way, one in particular. Her immune system is lousy at the moment and it seems like everytime I get her perked up from one potential illness another one springs up. I think they're both in need of some major protein. I know that plain yogurt and black oil sunflower seeds are good sources. I've seen dry cat food discussed several times, but it sound like this one is controversial due to the sodium content. I've also seen tuna suggested, but I was wondering if sodium would also be a problem, though you can get "reduced sodium" tuna. Can I get some other suggestions of healthy protein sources, and some feedback on the sodium issue with cat food and possibly tuna? Also, is it possible to give them too much protein?
