Warm v cold

[andreah]

I have some eggs to hatch, where I would ordinarily keep them can be very cool through the day whilst I am out bit worried this will be too cold for eggs alternative is an open cupboard near boiler which would be normal room temp which is best place to keep them?

Depends when you want them to hatch. Keep em at room temperature but if you want em to hatch quickly put them somewhere warmer or near a desk lamp with normal lightbulb.

I kept them in our livingroom (22-24°C, It's to frikkin' hot in here... *sigh*) and my eggs hatched in 12 days!
(I didn't realise that a warmer temperature would make them hatch faster.)

Not so much bothered about the length of time it takes just a bit worried the cool room may be too cold are they better normal room temp than cold

I suggest the following guidance. 15- 20 C is fine. For the first day or two after the eggs are laid keep the temperature above 10 C. After that 15-24 C will produce development at a reasonable pace but temperature dips do not matter.

You can delay development by refrigeration for a week or two but early eggs should not be chilled as they are often harmed.

Chilling to just above freezing in the first 24 hours after laying results in inhibition of the last division of the oocyte, resulting in triploid embryos, many of these die, some live on as unhealthy individuals and some appear normal but have breeding problems.

In general axolotls tolerate cold well: newly laid eggs are a key exception.

Thanks for your advice its very helpful i will keep them in the warmer area for now then

I raised mine at 13c. Took them about 3 weeks longer to hatch than their warmer counterparts!
