I just noticed that one of my 13 little 3 week old babies had a bloody tail! It looks like half of the tail feathers are missing and the skin around the area is purple. I didn't see the culprit/culprits. Not knowing what to do, we enlarged the brooder area and gave the girls lots of fun things to peck at as a distraction (corn cobs, lettuce, and a chick treat thingy on a stick). I read somewhere to put Vicks Vapo rub on the area (since it tastes like poo) but I'm not sure how to handle this. I have done lots of reading and it seems like there are as many opinions as there are breeds of chickens! We are first time "parents" but have done so much research that our brains are mush....I am worried! Help!
