No for the first generation cross she needed to bring in a brown egg layer. She would breed all those offspring back to true Ameraucanas for body type and egg color. After 8 generations the bird is practically pure.
The 3 eggs pointed to by the arrows are probably from the Mottled Ameraucana as they are too green to be pure Ameraucanas eggs. The rest of the eggs are blue enough to have come from true Ameraucanas.
