I have a sportmans incubator. It had 3 trays but I removed the bottom one so I can put the eggs there for lockwon. On the 2 trays I have left I lay my eggs down. It has an automatic turner. I've been trying to figure out how to increase my hatching rate and I thought putting the eggs in egg trays would help. But, with some eggs I can't tell which is the small end and which is the big end...
