We are new at the chick thing so forgive me if I am asking a dumb question. We have 8 baby chicks and they have started smelling bad. At first I thought it was the living area so I would clean everyday then I realized it was the chicks themselves. Five of them are two and half weeks old and the other three are four weeks old. Is this normal and what can I do to minimize the odor? They are in the house since it is still to cold outside and the hubby is still working on their home.
