Under the Crossbows Act 1987, crossbows cannot be bought or sold in England, Wales or Scotland by or to those under 18. Possession is also prohibited by those under 18 years old except under adult supervision. The act states that crossbows may be used by persons under 18 years of age only when supervised by a person aged 21 years old or over. Similar prohibitions for Northern Ireland are made in the Crossbows (Northern Ireland) Order 1988. Section 5 of the Wildlife and Countryside Act 1981 prevents their use for hunting birds. In Scotland, section 50 of the Civic Government (Scotland) Act 1982 makes it illegal to be drunk in a public place in possession of a crossbow.

Because of their iconic stature, the ruby slippers are now considered among the most treasured and valuable items of film memorabilia. As is customary for important props, a number of pairs were made for the film, though the exact number is unknown. Five pairs are known to have survived; one pair was stolen in August 2005 and has never been recovered.
 Question: did they ever find the stolen ruby slippers Context: The eggs are oval, white, and coarsely textured. All species normally lay at least two eggs; the usual clutch size is one to three, rarely up to six. Both sexes incubate with the eggs on top of or below the feet; they may display when changing shifts. Incubation takes 30--36 days; hatching success for undisturbed pairs can be as high as 95%, but because of sibling competition or siblicide, in the wild, usually all but one nestling dies within the first few weeks (later in the pink-backed and spot-billed species). Both parents feed their young. Small chicks are fed by regurgitation; after about a week, they are able to put their heads into their parents' pouches and feed themselves. Sometimes before, or especially after, being fed, they may seem to have a seizure that ends in falling unconscious; the reason is not clearly known.
