First time with chickens. I have a 6 day old chick that for the last 2 days has been chirping very very loudly all while going in circles very fast or walking backwards, kinda out of control. He then sits down and rests. He does this several times a day. There are times he seems fine, pecking around normally. He is smaller than the other chicks. I've seen him eat and drink, but not as much as the others - he sleeps alot. There was a few times he wasn't able to stand up. He his a silver-laced cochin. I have 25 chicks total and all set up nice in our house (heated porch) for now, with organic feed and constant fresh water. I picked him up awhile ago - I checked his crop and it seems kinda squshy - like its liquid filled and warm. I separated him right away - gave him some soft food and seemed to pep up - so I put him back w/the others but still not doing good. All the other chicks are very healthy although I did loose one right away - within 48 hrs - it was fine in the late afternoon and by late evening he was gone - found it listless and died shortly after. Do you think this might be related? And - my chicks were not vaccinated. Thanks for any help - its appreciated.
