I don't have a lot of experience so when my adult dimidiata laid eggs I decided it knew best and I left them where they were. And they all hatched. But, if you weren't gonna keep them all you'd have to disturb them and many people report having success with them out of the tank.
Point to make here is that Archachatina eggs are quite different. They are much bigger and much tougher and Annette's site documents just how thick and the fact that the babies were struggling to get out. I don't think there is much risk of them being squashed particularly.
Originally when you asked me Correne, I suggested removing them because I'd read in various places that the snails often disturb the eggs and can eat them.
My eggs were pressed up to the side of the tank and fairly wet, it's not like they needed to be coated in soil to hatch, perhaps the opposite is better.
The margie (spp. ovum) breeding paper I got hold of suggested that dryness caused the most deaths. Apparently the eggs can almost survive free-standing water. But Christabel has success hatching margie (spp. suturalis?) eggs out of the tank, spraying them when they look dry. As she said, she doesn't do anything special and they hatch. We talked long about this and incubation temperature and we wondered if suturalis are easier to hatch than other sub-species possibly because they originate from the only temperate area of Africa, where the tropical spread never reached.
I was really nervous when my fulicas laid their first egg's. I didn't want to move the egg's, but I worried the snails would eat or crush them. So I moved the snails to another terrarium, and left the eggies were they were. And they all hatched. Second time I wasnt worried anymore, and I moved the egg's to smaller terrarium. And again they hatched. Third time I left the egg's to the terrarium with the adult snails, and gues what? They hatched!
Well... Im not sure I should tell... Please dont be mad at me!
My friend has a tortoise that eats snails. Okei, there, I said it. Now you all hate me.
To justify myself, tortoise was rescued from very bad place, and we had trouble getting him eat anything. But he loves snails, and well fedd baby fulicas are healthy dinner for him. Lot of calsium. I do feel sad about snails, and I allwais leave some of the babies to grow. Babies all well taken care of, and they wont suffer much.
I will never forget when my tender and adorable snail was devouring its own eggs, it is not good, landsnails practice the cannibalism with its own eggs (Because this mechanism favors the control of the population in the nature). The first snails that are born even must be separated because the fertilized eggs eat as much as not fertilizedin any case, they eat inmediately other food (Remember to feed them for its development well).
I'm pretty sure my snails will have their first batch of eggs soon, and I have a friend who is interested in adopting a snail from me, is it okay to keep one single egg and destroy the rest or do they need to hatch in groups? And also how big should the snail be before I give it away?
Couple of months ago I had Helix Aspersa babies. I thought I'd remove them to a seperate tank for safety reasons. They suddenly died out and I thought because of no mums or dads or I might just be doing something wrong.
But if I ever egt any babies again. I'd keep them in the same tank. For a test.
woo hoo i have just found 7 huge eggs in the margie tank i am so chuffed mind you one has a small dent with jelly coming out so im presuming that is has been damaged by the parents i have now removed the eggs along with all the surounding soil so they did not turn or move and have put these in a smaller tub next to the parent tank i still cant get over the size of the eggs i put a pound coin near the eggs and it was the same size any infor on incubation times? these could be 2 weeks old as that was the last time i went digging in the tank i only found these as i was doing a last check befor the snails went in their now snail room
