I don’t know as I’m in UK but I can suggest a great alternative... corrugated plastic floor protection sheets (we call it Proplex here) available at most large DIY stores or builders merchants. It comes in 8x4 sheets. I use two sheets folded in half lengthways and bent round to form a ring, held together with bulldog clips. It’s about £3 a sheet and can be disinfected afterwards reused many times and adjusted as your chicks grow. The bulldog clips also secure the netting as it hooks over them. Perfect solution and the best I’ve found.
