Our hatch day is Tuesday. Eva came out yesterday and took a nice dust bath, ate and drank. I used that time to check on the 7 eggs. 1 was not good - had to toss it. So - 6 eggs now. I ordered 3 chicks to be delivered Thursday morning from Meyers (my fave Hatchery). Just in case the hatch does not go well, I want her to have chicks to raise. My plan is to let her hatch the eggs on Tuesday thru Thursday with no intervention from me. Let her handle it. Thursday night, slink out and put the hatchery chicks under her along with whatever she has hatched. Hopefully in the morning when chicks come out from under her, she does not notice the new additions. I watched several UTube videos about it and it seems to work most of the time. Since she is only sitting on 6 viable eggs, adding a few more should not be that noticeable to her?? I hope.
