Hello. This is a first for me. Today, my red- eared slider laid an egg on my living room floor. She lives alone in her tank so it came as a shock when i saw the egg. It is about an inch and a half long, yellowish white like a pebble. What should i do with the egg? And what sort of behaviour is normal for my turtle now? My turtle is about 5 years old. Thanks very much for your help.
