Fig. 10.

Stage 41 (11.5 days) quail embryo. The length of the feather germs is increased over the whole embryo. White feather germs are apparent throughout the length of the embryo, the most noticeable being ventral to the eye and towards the beak. Pigmentation on the feet is more prominent, particularly around the metatarsal joint. Specific pigmentation patterns are not shown from stage 41 onwards as there is increased variation between embryos. The beak and third toe lengths are unchanged at 2.0 and 6.1 mm, respectively.
