It doesn't look shrink wrapped to me. The ones I've had to "steam up" have had membranes much whiter and more opaque than that. The membrane looks a bit thicker than usual, but not really dry. If it were my chick, I'd give it a bit longer before intervening, especially since the chick's got plenty of air. If the membrane starts to turn white, you can touch it lightly to see if it feels like it's stiffening. A "shrink job" is stiff to the touch and obscures any view of the veins. And also, X2 on the type of chicken ... the egg looks 2 kool!
