We have 4 hens. Last Friday night, we left the door open to the coop possum finally got his chance.. All are living, NO signs of puncture wounds at all . One not affected at all and now seperated. One has one eye closed completelty. One has a Rodney Dangerfield eye and the other eye closed completely. Another has small wound on face. All 3 are very lethargic. Sleeping constantly.. I get them out to give water. Bought some antibiotics but i have to give to them by medicine syringe. Are they going to survive the trauma? I don't know what else to do.. HELP?
