We just got two pullets from the poultry show in Columbus, and have had them isolated with the other two birds we also got from the poultry show. The smallest one...she looks like a silkie but is actually another breed...I can't remember what she is. ..has been acting a bit quiet the last couple of days and today her eye is swollen shut. We treated it with eye wash and terramycin gel, but don't have any terramycin to give her orally, and due to the Holiday, can't get any today. We do have Tylan, but should we give her that, or just wait and see how she does? She doesn't seem to have any other symptoms, and ate breakfast this morning, but wasn't interested in any treats that I gave the others this afternoon. We changed their bedding from straw to shavings, in case it is mold or something in the straw, and have a heat light on the pen, which she appreciates very much. We are reluctant to separate her from the others, because she is so terrified when she is by herself.
