Western fence lizards mate in the spring, and do not breed until the spring of their second year. Females lay eggs under a flat surface by digging a nest at night. She lays one to three clutches of three to 17 eggs (usually eight) between April and July. The eggs hatch in August. [5] [6]
The common garden skink is oviparous [1] and lays small white eggs between summer and mid autumn. The female usually lays about six eggs, often in communal clutches that may contain as many as 250 eggs altogether, usually under a cluster of rocks to keep them safe from predators. The eggs hatch in a matter of weeks after they are laid.
The viviparous lizard, or common lizard, (Zootoca vivipara, formerly Lacerta vivipara) is a Eurasian lizard.It lives farther north than any other species of non-marine reptile, and is named for the fact that it is viviparous, meaning it gives birth to live young (although they will sometimes lay eggs normally).

If a nest is nearby, one can expect to see 10-30 lizards within the period of a month. In parts of the southern United States, nests are commonly found in houses and apartments, especially along the coast. The nest is where the skink lays its small white eggs, up to 4-8 at a time. [17]
In most lizards, the eggs have leathery shells to allow for the exchange of water, although more arid-living species have calcified shells to retain water. Inside the eggs, the embryos use nutrients from the yolk. Parental care is uncommon and the female usually abandons the eggs after laying them.
Reproduction occurs through parthenogenesis, with up to four unfertilized eggs being laid in mid summer, and hatching approximately eight weeks later. The New Mexico whiptail lizard is a crossbreed of a western whiptail, which lives in the desert, and the little striped whiptail, which favors grasslands. The whiptail engages in mating behavior ...
The eggs of the egg-laying mammals (the platypus and the echidnas) are macrolecithal eggs very much like those of reptiles. The eggs of marsupials are likewise macrolecithal, but rather small, and develop inside the body of the female, but do not form a placenta .
The female Plestiodon will lay its eggs in June, and four to six weeks after the incubation, the young hatch. Thus the birthing process consists of laying eggs and external incubation. [ 16 ] Fertilization occur shortly after copulation, unlike many other lizard species Plestiodon fasciatus females are unable to store sperm between successive ...
