Hi,can anyone help please I have 2 Black silkie hens sitting on eggs, when I went to take them off yesterday 1 of them had left her eggs, the eggs were cold so i put her back in with the others and put the eggs in the incubator (eggs due in 4 days). This morning I was going to swap the nest box over (better box) to the remaining broody only to find it full of mite Both hens were sitting in the same indoor pen just divided in half by a wooden divider. Is it safe to treat the other broody for mite and how can I stop the mite going on the newly hatched chicks
