I missed all that! Great catch!
Receptive is when your little lady is sexually mature and is ready and wanting to mate. I think of it as she gets all dressed up and is searching for a man. Basically, she is in heat. It always comes before being gravid, or ready to lay eggs.
Since egg laying takes a great deal out of our sweet ladies and shortens their lives, we try to reduce not only the number of eggs they produce, but the frequency that they produce them. Keeping your basking temps no higher than around 80 and limiting feeding to 3-4 feeders, 3 days a week is how we do this. As they are still growing and need nutrients, I‘m very iffy about starting this regimen until after they’ve laid for the first time.
I have 2 lady veileds and this is what I do for them. Both are around 2 years old and each one has laid only twice. One went almost an entire year between laying. The other hasn’t laid since Feb 2020.
Having your husbandry as perfect as possible is essential so that they won’t have any problems laying their eggs.
Regarding the supplements (that I missed), you can either get a multivitamin without D3 and then you’ll use that and the calcium with D3 one feeding every other week for each, rotating them so they aren’t given together. Or, just use the multivitamin with D3 at one feeding every other week. I use Reptivite with D3 as it also contains preformed vitamin A which is good for eye health.
Having the correct uvb (I missed this too) is absolutely needed. The long light that you have...is that your uvb? If so, I’m guessing it is a T8 fixture. Those can be used, but the bulb would have to be a 10.0 or 12% strength. T5 with a 5.0 or 6% bulb is recommended as it is better. You also need to have it span the width of your enclosure. Right now, as she basks she isn’t really getting adequate uvb levels. The 2 lights should be closer to each other.
It would also be a good idea to add more branches and vines for her to travel on.
Here’s a pic of one of my enclosures to give you an idea. It isn’t as pretty as I’d like, but it makes my chams happy.
