[1] Ram lambs that will be slaughtered or separated from ewes before sexual maturity are not usually castrated. [23] In most breeds, lambs' tails are docked for health reasons. [8]
Oviparity occurs in all birds, most reptiles, some fishes, and most arthropods. Among mammals , monotremes (four species of echidna , and the platypus ) are uniquely oviparous. In all but special cases of both ovuliparity and oviparity, the overwhelming source of nourishment for the embryo is the nutrients stored in the yolk, pre-deposited in ...

In the latter, the eggs develop in utero for about 28 days, with only about 10 days of external incubation (in contrast to a chicken egg, which spends about one day in tract and 21 days externally). [11] After laying her eggs, the female curls around them.
Providing birds with a safe and warm space is just as vital as extra food at this time of year. "Robins often use nest boxes as roosting sites during the winter, so putting up a suitable nest box ...
