I have a Farm Innovators 4250 Incubator that has a model 3400 Farm innovtors egg turner in it that has worked quite well for incubation and hatching of chicken eggs. I wanted to start incubating Coturnix quail eggs so I went on Amazon and ordered the Little Giant quail rails because there was a review stating that they would work with the Farm Innovators egg turner. I installed the rails and I cannot get them to turn --- it's like the pin that slides up and down the groove jams and will not turn the eggs. Has anyone else experienced this? I have now found Farm Innovators quail rails for sale, but they seem to look just like the Little Giant quail rails. Thank you in advance for your help.
