I sure don’t count on that many pullets. . I need to sell 8 or 9 if such a wonder happens.Good luck!! Hopefully they all hatch... all hens of course!!
I bought this many eggs because of earlier experiences with bought eggs.
First try (Naine de Tournaisis) 12 eggs, 3 chicks (2 girls). Maybe the eggs were too long in a warm car?
Second try (Rhode island red bantams) 10 eggs, 3 chicks (2 girls). There was a lot of fuss with 2 competing broodies sitting next to each other. One nest was abandoned so they could sit together.
The 2 times I had broodies with my own eggs, having a rooster, I had more chicks.
First try: 12 eggs, 6 chicks (3 girls). 5 eggs were a bit older and not kept as advised.
Second try: 7 eggs, 5 chicks (only 1 girl).
So my guts/chance experience/ told me I should buy more than 7 eggs to be sure to get 2 females for keep.
