I just got a sportsman hatcher and am planning on moving my first set in on Thursday. There are metal trays with lids in the 1550 and I'm wondering if I should use the tray liners in them for non-skid. However the tiny hardware cloth is non-skid itself I believe. Also, these seem soooo shallow to keep chicks in for any length of time especially with the lids on? I can see for my quail but for chicks and ducklings they seem so shallow. Any tips or ideas from anyone who has one?
