Our peachicks are about 4 months old now, and have been slowly being introduced to free range. I brought them into the barn last night, locked everyone up. They are in with a few chickens (6), but have been for several days with no issues. The peachicks normally fly up into the rafters for the night. Went in this morning to check on everyone and let them out for the day. I couldn't find the two of them.... I ended up finding one peachick in the water trough, soaked. I took her out and saw that she has a huge wound on a wing. Looks like its down to the bone, although nothing appears to be broken. She is missing feathers. I took her up the house, gave her a bath to clean her and the wound off with warm water, cleaned it with betadine, and applied blue kote. She is now wrapped in a box in the house where it is nice and warm. She's alert, eating and drinking small amounts when offered, and preening herself. I did also apply an antibotic ointment for now. I have Pen. injectable at the house from the chickens when one had an infection--Can this be used? It is about a year old though... I also have Trimethoprim sulfa (TMS), however that is even older and commonly used to treat uri in animals. The other peachick is gone. No clue where he is, and he normally answers or comes when I whistle to him. I don't see any feathers, and did not see a body. I don't know if he's just staying hidden, or if he's just gone? He normally does not leave her side either.
