Molting?

[kelbel313]

Help! I brought my hen inside because I assumed she had worms. She had also been broody for over a month so she was skinnier than the rest of the girls and hadn't laid an egg in over a month. I started her on a dewormer and she perked up immediately. Her comb went from pale and dry to red and plump and she seemed to brighten up. Suddenly over the past week she started molting..at least that's what I hope it is. They've never molted before so I don't know if this is normal. Over the past week she has lost nearly all of the feathers from the base of her neck down. Even tail and wing feathers. She's still eating but she is wobbly when walking..could the feather loss be causing her loss of balance? Help!!!!
