I had similar incident with jumbos and automatic turner when I started using new incubatorArrived and snug in the incubator - should hatch on time. They arrived in one piece but one of the jumbos had an accident in the automatic egg turnerthey don't fit very well and if I'd known I would've swapped the last row out for the chicken-sized one to prevent escapes
I moved as many as I could to the far turner and so far no more crushing haha. Although the turner is listing a little under the weight yikesI had similar incident with jumbos and automatic turner when I started using new incubator

Yes! I got a puppy on Saturday so I've been super busy and not on much, but they did and I set them
And excited about new puppers too!!!!
