So I have my ASFs in a plastic tub and I have the 1/2 cloth on the top. I want to put my breeding colony in a tub but when they have babies I know that the babies would be able to fit through the 1/2 cloth. If I use 1/4 cloth for the top that's not the issue. Should I still use 1/2 for the hopper or could I use 1/4 for the hopper? I'm just scared that if I use 1/4 for the hopper then they wouldn't be able to get the food out. I really need some advice on this from someone that has a little more experience in this area!!
