I have 11 Silkie chicks ranging in age from 5 to 10 weeks. One of the smaller ones has become sick (or injured) in the last 3 days. Its feet have drawn up and sometimes it twists it head completely upside down. I have still been able to get it to eat and drink a little. Does anyone know what causes this, and is it a sickness that is contagious to the other chicks? If this is not a sickness, has the chick been stepped on or pecked? Is there any hope for this little guy or is it just a matter of time. I would appreciate any help or advice than can be offered.
