Five week old chicks are in the aviary with 25 week olds so I set up an area where they can go hide if need. The chick’s food and water is in the protected area. They kept getting dirt, leafs, etc in the water so I placed a piece of plywood under the water. Today I looked under the plywood and found it full of a hairy brown mold. Should I remove all the leaves, twigs, and the top layer of dirt from the aviary and disinfect it ?
