When I went to check on the keets that are with the silkies I noticed the youngest/smallest one was sitting not running around with the other 2. She would get up, take a few steps, and then sit back down. I let them all out of their cage into the run to get a better look at her. She did the same thing in the run. I brought her into the house to examine her but found nothing wrong with either leg or foot, that I could see. I gave her some polyvisol without iron, put some antibiotic ointment on her legs and feet, just in case then put her back out in her cage with the others. This morning she seemed to be taking a few more steps but still sitting mostly so I brought her in and put her in a small bin with a light and gave her some more vitamins. She is eating, or at least picking at the food. She is definitely drinking and her poo was not abnormal yesterday or today. She does seem to be using her wings for balance and is not holding her feathers tight to her. Her crop feels normal and no pasty butt. She will be 4 weeks old on Wednesday and is smaller then the other 2 that are a few days older then her. She is not doing a lot of peeping but she is the quiet one out of the 3 so it's hard to tell. She is setting in the bin under the light but doesn't seem to be shivering. She is in an upright position not leaning or tipping while she sits. Anything else I can do for her?
