Sort of like a corn pad!@Saaniya , a thought for your bird, since it's walking on floors. Making a donut shaped pad to go around the wound and take pressure off the wound itself may be helpful in your case. I've made them from pool noodle foam and from craft foam (the denser craft foam holds up better). Cut a circle that will fit the foot pad with an opening in the center the size of the wound, I put a piece of gauze down, then the pad, then wrap the foot to keep it in place. It will cushion the wound and may help with healing.
Our friend @Saaniya is in Delhi, she may have to improvise, but I love where you’re going with this concept !
