Is she the only chick or why would she always hang around with the ducks?
Ducks are very sweet but always messy and humid and their typal bacterial range is not very healthy for chickens even more so for young chicks to grow up with.
This is also one of the reasons it is advisable to keep them in separate coops. The ducks bacteria range even effects the hatchability of chicken eggs in quite a bad way, they tend do die from these bacteria around day 12.
