I got my chicks yesterday. 8 of the 12 made it through shipping. One looked funny yesterday. She kept walking backwards and seemed not to be able to settle. I put them under a heat lamp immediately and gave them all sugar water and food. They all seemed to be find by last night. Everyone seemed to be fine though out the day today as well. About an hour ago though, my little white leghorn (not the same one that was acting funny yesterday) started mouth breathing and hasn't stopped. I am very worried about her. I've given her more sugar water. What else can I do for her? Thanks.
