my 2 year old Rhode Island Red Hen got her head slammed in a door today. She appears to have nothing broken however her eye is permanently shut and she's walking very much like her equilibrium is off. I encourage her to drink and she did and swallowed, she also clocked in her neck is not broken. Since she is more of a backyard pet chicken, I never lock her in the coop but I did so just so she would have a smaller space to get her bearings. what is the next step? There is no blood and she's holding her head up right and even walks around slowly. there is no wound to treat, so I'm a little in the dark as to what I should do besides keeping her contained with food and water.
