What type of fence is that? Plastic? Haven't seen this large holes on a metal fence? Would it stop animals passing through? Anything larger than 5 cm square seem too wide. Our neighbors hens pass through 10 çm without any problems... And eat our garden!
Its a metal fence. It is often used in our region for fencing farm animals. It is the cheapest :) It is not very visible on photo, but the fence cell at the bottom is small (about 2x5 cm) and increases upward. Hens will not pass :)
