Heavy Duty Pen sheeting, ideal for protecting the sides of the chicken run and prevent wind and rain driving in to the run.  Simply staple it to the sides of the run.
 
We sell it by the metre  and have it available in 2 widths.  If you order x3 you will receive 3 metres of your selected width.
 
The sheeting will be sent folded and may be creased on arrival so will need laying flat before fitting.
