A 17-year-old boy from Hereford has been charged with possession of a bladed article and section 20 assault.
It follows an assault in Luard Walk, Hunderton on Tuesday.
He is set to appear at Kidderminster Magistrates' Court this morning.
A 52-year-old woman from Hereford previously arrested on suspicion of assisting an offender was released with no further action.
Sheds housing nearly 200,000 broiler chickens at a Herefordshire farm are to be demolished and rebuilt to a higher standard.
