A better picture would help. From the side as Tom suggests. What I see there would bother me as far as pyramiding starting. I would be concerned about the growth especially what we are seeing between vertebral 2 & 3. The keratin is not growing in smooth. Way too much humps and valleys forming. I like to see smooth growth, especially at such an early stage. Looks like about 6 weeks of growth. Although a different species, here is what I like to see at 8 weeks. Stars are just as prone to pyramiding as redfoot. I'll post full size image so you can zoom in. Look at the way the new seams are developing compared to yours...
