Hello, My 10-month old bantam Sebright hen has a swollen foot. Upon examining the bottom, the center pad has what looks like a scab on it. The swelling is visible from the top as well as the bottom. She is not favoring it, but it is definitely very swollen and feels slightly warm. I don't know if she has a splinter or something stuck in her foot underneath the scab. I am worried it is infected and have no idea what to do as far a antibiotics. I am attaching a photo. Thank you in advance for any advice.
