We have 2 week old chicks. One is sick or injured. She stays huddled up under the heat lamp. She will not lift her head up (straighten out her neck) but keeps her head tight to herself in her huddle. She barely moves. She is not growing like the others. I first noticed she was not right a few days ago but hoped she would come around. No luck. She walks fine when she walks and spent the first couple of days standing in a huddle but now is laying down in a huddle. I doubt there is much I can do but hope. Does anyone have any suggestions or thoughts?
