One of my really fluffy hens apparently prolapsed an egg and tore her self. I noticed her away from the flock and picked her up. Her wounds are full of maggots. I rinsed out what I could and used a syringe full of water to get more out but I can't get them all out. I mixed some iodine with water and put that on the wound. Should I just put her down? She does not look like she feels good. I don't know what else to try
