Egg-laying animals refer to animals that reproduce by laying eggs. Birds, reptiles and most fish and insects are ovipositors, so are swallows. 14- 15 days later, the young birds are fed together, fly out after feeding for about 20 days, and feed themselves after feeding for 5-6 days.
It takes about 14- 15 days for swallows to lay eggs from May to early June and from mid-June to early July. Both male and female birds should hatch eggs together, and the young birds should be fed with their parents after hatching. Swallows can fly in about 20 days and leave their nests in about two months. Swallow is a general term for 74 species of birds of passeriformes and Yanidae.
