I have a very young rooster (~ 4 months old) with problems in walking and standing on his feet. I have no clue what can be wrong. In the past he had problems with parasites. So at the moment i am giving deworming medication and also some yogurt to make sure that he will get calcium. Any idea what the problem may be? By the way in the past few weeks i had problems with mycoplasma in my flock.
