I am incubating 6 call duck eggs in a Lyons TX-7 incubator. We have been hand turning since the metal thing that the eggs sit in above the grate was too small. We received the new chicken egg size grate today. But the eggs won't stay straight in the space with the large end up. It just pushes them and they can turn sides ways. Can someone tell me if this is the way its is supposed to work or what we are doing wrong. Maybe there is a DIY fix! We planning on going to a poultry show on Jan. 9th and would be gone 2 days and a night. Don't guess we'll be going if we can't fugure this out. Thanks in advance for any ideas.
