They take a while to grow up big enough to feed. Tripling the weight of a newly hatched silkworm doesn't look like they've grown at all but they actually have.
Fiddling around with a syringe is just too much work and mess for me. Do you have it completely covered in the fridge? How long does will your food last per the manufacturer?
Do I have the chow covered in the fridge? Yes, it is in a tupperware. I'm not sure if i understand your second question. Once cooked, from coastal silkworms it says it'll last a month in the fridge. I don't know if I cooked it up correctly, but they have been eating it when it's fresh. What I did to rehydrate was use the synringe and directly dribble a few drops of water onto the food that the worms are on. I'm afraid that may have killed them...
If I've left the wrap off the bowl of cooked chow and it has dried out in the fridge, I'll just add a bit of water the the top and rehydrate the skin on the top without making a mucky mess. If I've over fed and the chow in the box of silkworms has dried out, I just leave it in the box and try to feed less--idealy only as much as they will finish in a few hours which is hard to calculate when they are very little. Dried out chow in the silkworm box is garbage. I would never try to rehydrate it. I will only moisten the chow in the fridge. Keep it sealed in the fridge. Understood.
I do not understand why you would have a space heater at the same time you are running your a/c unit. Just find the warmest part of the house for them--and don't cook them in the sun. My chameleon room is a very cold room in the winter. I just put them on the shelves above the lighting. They got quite cold at night and I don't think they ever got anywhere near 80F. They grew just fine, albeit slowly.The AC is on because I live at home with my family, and don't have control over whether or not it is on or off. I won't be using the space heater anymore, but I am using a light bulb. As per your suggestoin, I think I'll no longer use any heat source and play it safe
I don't put any lid on them. I let them grow up before I change them. The food dries out and doesn't cause a problem for them.So you leave the old dry food in the silkworm bin?
Some chameleons love silk worms, some don't. Some go through phases of eating them and then go off them for awhile. If you have a chameleon who is not eating a lot--and what does "not been eating much" mean to you?--there may be some health issue going on which should be investigated. Healthy chameleons should eat. If they don't, there's a problem. Mature chameleons eat less than growing ones, so you will notice a drop in appetite as the animal matures which can sometimes be worrying. Have you taken a regular weight on your animal with a good, reliable scale? Weights tell you a lot about the condition of your animal.
