You can put them all in lock down on day 18 for the first batch and they will be fine or you can wait an extra day and split the difference...I have had no problems doing it either way on some batches like that!! GOOD LUCK!!
Have a question..... I put eggs in an incubator on a Wed afternoon. Then we added more on Friday afternoon. When do you think I should take them out of the turner? Is there a happy medium?
Thanks
