I have a group of aproxamitly 6 week old chicks. One, and only one, started bloting at the base of her neck a few days ago. I called around trying to find a vet who could help me (my merk manual has magicly disappeared). I FINALLY found one who could help over the phone since the closest one is 3 hours ago. They said it sounded like an over full gizzard and to turn her upside down and "milk" the fluid out. I did this tonight and it helped but its still swollen. I figured I would give her time to rest and try again in the morning. She started eating almost as soon as I put her back in with the rest. Is there any way to prevent this from happening again? Is this caused by over eating or eating to fast? They have ample free choice feed and water 24/7. I dont have the time or patience to keep this up with her every day.
