This little hen just came off a nest with chicks about a week ago. a couple days after she came off the nest i noticed she had some blood around her eye. i thought maybe she did not like the brooding pen she is in and was trying to poke her head thru the 1" mesh wire. i have been keeping an eye on it but today it is much worse. One eye is almost swelled shut the other is very swollen. Does anyone know what this is? Her poo is solid and she is breathing good no raspy sounds or head shaking. She is eating medicated chick starter and has fresh water daily.
