Her eye is swollen shut :(

[Stones_Chickens]

I was keeping chickie (a stray NZ mix doe) in a bottom cage and Belldandy (mini lop doe) in a top cage with her mini lop mix baby. During feeding time I opened the top cage and Belldandy ran straight down into the bottom cage (originally one large cage for mini lop and her baby). She immediately started attacking Chickie and appears to got her eye. I cleaned it several times with warm water, but now it is all swollen shut. Do I just keep it clean and the swelling will go down on it's own? Before it became swollen she was using the eye and appeared to be seeing out of it.

Unfortunately Chickie is very untame and hard to handle, I had her in with the two other strays I have (but they are male and were beating her up).
