My veiled just laid her first clutch yesterday she is aprox 8 months but I know that it can happen earlier. But trust me I was worried that I would not know when. They will let you know she will go to the bottom and start scratching alot and if you put her back at the top she will continue to go back down. She will not be eating as much or may stop eating all together. She will also look like her belly is really swollen. We nicked name our girl Jabba as she looked like Jabba from star wars she was so fat.
