This is our first flock and Pecking Order just took on a whole new meaning. One of our Barred Rocks we had taken to calling "Loner" because she was rarely with the others. On Friday, she disappeared completely for hours when the flock was out in the yard and we assumed the worst, but luckily returned to us. Our unintentional rooster and his beta hen are the bosses. All around 18 weeks old and Roo has started aggressively mating with them all - even the second Loner was returned to the coop after her absence. Sunday, when we were fetching Loner from an unusual resting spot, about 10 yards into the woods on our property (maybe an egg, we thought), we noticed her eye was shut and had dark yellow mucous in it and we assumed an illness and brought her to the vet. Turns out, it was a perforated eye - most likely from being pecked at. WTH!! Probably why she ran away on Friday. Now she's in the brooder by herself and on medication/eye drops. Not sure how we're going to reincorporate her if they're beating up on her like this! Any ideas? PS - Thankful for this online community because I came here first to research the eye discharge and saw that there is a very infectious eye thing that chickens can get and hence the Sunday vet visit.
