Here is my experience if it's bad. My hen was trying to eat the pellets falling out of my horses mouth and my filly stomped on her and broke her foot. I sprayed Vetericyn Hydrogel spray on it three times a day and left her alone, except for the first week in which I immobilized the leg and foot with a metal finger splint but left it open to breathe. It was a slow, long and probably painful (at first) healing process, but it never got infected and three toes died off, dried out and fell off. Now she is now a one toed hen with a deformed foot but she is healthy, active and fully healed. I had talked to my vet about amputating the foot early on, but he said as long as she was mobile, eating and drinking and there was no infection, we would try the Vetericyn Hydrogel (miracle spray) and see how it went. I always try to use the least invasive and most natural treatment and this worked for us. I have 50 free range laying hens and meat chickens and have never lost one to illness or disease. I use food grade DE (Diatemaceous Earth) in the hen house and nest boxes, I put it in their food as well, and have an area where they can dust in it. I also dust them occasionally with the DE. I also put apple cider vinegar in their waterers.
