Hey all,

I have a female Mossy's she's great shedding (so far twice in 2 months), eating, growing, laid 8 infertiles in 3months, and she seems as large as ever physically. Appears larger/swollen compard to my slender male Mossy.

Well her sacs have continued to get larger over time, and now I noticed this morning her calcium sacs are soo large, that I can see them easily protruding from her skin a bit (as if she eyeballs underneath her skin) when viewed from the TOP of her head, dorsally that is.

I feed her crickets everyother day, she's eating at least 6 every feeding, they are large 3/4-1" crickets dusted with TRex's Bone Aid.

I just wanted to make sure this wasn't considered unhealthy. She's the first female I have owned.

chalk sacs are a good thing to have if she's laying. from what i could understand by the book, the chalk sacs should go down a bit after she lays eggs, or gets out of reproductive mode. the purpose of the chalk sacs is basically to hold a milky calcium substance. now i have heard of chalk sacs getting so big that they obstruct the pathway for food, but not particularly with any uroplatus. since the substance is squishy, most geckos should be able to push any food down. my two female pietschmannis have had pretty big chalk sacs the past few months, and they have been good eaters ever since i first got them. since i realized that their calcium reserves were beyond sufficient and they werent even breeding, i cut back on the frequency with which i would dust their crickets. been doing that for probably 2 months now and one's sacs have reduced to about half the normal size, the other now just has what looks like a fat neck. if i ever notice any breeding, ill start beefing them up again, but at this point they seem to be healthy and have some of their reserves still visible. in your case, if they seem large enough to where your gecko is "pushing back" its meals (like how you see a snake "pushing back a mouse after it gets it in the mouth), i would say cut back on the supplement. still give some, but cut it back. at least you know your mossy isnt having problems feeding.

Thanks a lot...I will keep on the feeding schedule I have.
