Can I put them back with the parents? Or leave them in a box with a heat source...till when? And I heard I can use a reptile rock in the box as warmth so they can get warm if they want or cool down if they want! I do not want to use a heat lamp!! So any other suggustions on how to keep them warm that does not include a light bulb?!! Please any and all information is welcome but if you have real experience we love to hear from you the most!! Thank you all!!
