They are 2 1/2 months old, seperated from my 5 1/2 month old chickens for now. About a month ago i noticed one's beak was misaligned and this chicken always looks unkempt and wet and is lookimg worse everyday. She makes a huge mess when she eats and drinks and obviously cant groom herself well or protect herself because of her beak! She isnt underweight it seems. What do I do here?
