Do you have a proper UVB light on the cage?
I read information in aother post of yours...I would recommend that you improve your feeding/gutloading...I use dandelion greens, kale, endive, escarole, collards, carrots, squash, zucchini, sweet potato, sweet red pepper, and a bit of fruit such as apples, pears, berries, melon.
Also it's recommended that you dust the insects just before feeding them to the chameleon at almost every feeding with a phosphorous-free calcium powder... Twice a month with a phosphorous-free calcium/D3 powder and twice a month with a vitamin powder.
It looks like she may be developing MBD and it needs to be stopped ASAP to prevent any harm to her.
Her supplements, basking temperature, feeding/gutloading of the insects, proper UVB needs to be spot on. She may need some liquid calcium sandoz or gluconate to build up her calcium levels. This is particularly important since she will be producing eggs soon by the look of her colors.
I'm would also recommend that you put an opaque container at least 12" x 12" deep x 8" full of washed playsand in her cage so she can dig to show you when she's ready to lay eggs. Also...don't let her see you watching her when she's digging. It causes them to abandon the hole.
