It seems to me that the "lower corner block glyph" seems to be painted using two different shades of red.. On my screen the chicks head and the upper chisel seem to be more of a blue/red.
I mean in the area of rock erosion or flaking to the right of the first dark vertical fissure, but to the left of the second even larger vertical fissure
Whereas the chicks body seems to be more of an orange red.
In fact the shadows cast by these two fissures, the flash gun was to the left of the lens axis, seem to indicate that this area of rock has flaked away.??
The stray marks in the lower picture seem to be consistent with rubbing or smudging rather than being directly applied by a "stubby" ancient paintbrush or splashing. Less opaque and peak ridges not valleys.
Also it is interesting to note the "tram lining" present in the chicks tail and front leg. Obviously the "stubby" paintbrush had a defect. Bristle separation, a common fault even today.
The angular "flat chested", straight tailed, angular appearance of this chick is entirely consistent with the use of an ancient "stubby" paintbrush.
So therefore I would say that the chick in your lower picture was at least mostly ancient. I do have a problem with the head.. flaked rock.. different hue.. brush ??
He was right handed.
I must take a close look at the "contentious cartouche" chicks.
