Welcome to BYC. Chicken worms have built up a resistance to Ivermectin, so a better alternative wormer would be SafeGuard horse wormer or the goat wormer. Regular 16-20% protein chicken feed should make up 90% of her diet, so that she gets all of the proper nutrients and vitamins. Some chickens will have dirty bottoms from too much fluff that can be trimmed occasionally, the stickiness of the poo, or from vent gleet. Her wobbly legs sound like a symptom of Mareks disease--was she vaccinated? How old is she?

thanks for your fast reply,she is about 3 and a half months old and i dont think she was vaccinated

'i have 6 chicks in total 3 that are vaccinated and 3 that are not she is the only one showing signs with her legs. I feel so sorry for her.
