Juvenile Greek tortoise ill?

I have 2 Greek tortoise juveniles. The younger (approximately 6 months) has a few odd behaviors that the older one (approximately 9 months) does not. My first inclination is respiratory infection. It does not have signs of runny and/or swollen eyes, nose or ears. But it pulls its head in and out of its shell sometimes in little bursts. Less often, I see it stretch its head all of the way upward and open its mouth wide, particularly after eating. No apparent loss of weight or appetite. Drinks water and sleeps a lot. Are these signs of illness?

Husbandry conditions: 4x3' tortoise table, coconut coir substrate, cool end 65-70 degrees, basking area (UVB, UVA & ceramic lamp) 95-100 degrees. Diet varied but includes dandelion, turnip, radish, & carrot greens, chicory, clover, plantain, petunia, viola, pansy, green/red/romaine lettuce, etc dusted with calcium daily, vitamin 1-2x per month. Wet mash of pellet (grass & hay) 1x per week. Soak 5 min every other day or so. Not hibernated.

Should I seek a Herp vet?
