Silkworms at two weeks

My silkworms were born on Feb 8th, 9th and 10th. There is a definite difference in sizes. Some have grown big and there are still some that are only about twice to three times the size they were when born. I can see the little 'horn' on the back of the cat. I could see their little legs yesterday. I can see the difference in size in the same day. I'm dividing them into separate containers until I only have about 10 to 20 in each one - depending on the size of the containers. I've been collecting TP and paper towel rolls but still don't have enough to make my little 'condos'. One of the problems I can have is mice or ants. Both will eat on the cats. They are safe from mice (fingers crossed that I don't have any. I haven't seen any signs that I might have them.) The ants could be a problem - if they come before they are finished. According to information that I have found online - if I find ants, I have to put four bowls down with glasses in the middle and the containers on top. I will have to put water in all four bowls. That will be FUN. I have eight containers now and will be putting part of four of them into other containers tomorrow. That would be twelve. I have three large plastic storage containers that I will use after that. Then I HOPE that someone has a birthday so I can get some more containers. lol
