Perek Shira: The Hen - Can You Afford To Have Another Child?
The Gemara says that a hen which lays an egg every day proves that Hashem has made creation with the possibility of giving forth offspring every day. Does the hen not worry who will support all these chicks? The smart little hen knows the secret of how this world really works; parents do not provide the child with food Hashem does. A newborn child is not a burden on his earthly parents already strained budget. Each child is also a child of Hashem's and is born with his own expense account from his Father in Heaven.
The Hen Sings "Nosen Lechem L'Chal Basar Ki L'Olam Chasdo"; Hashem provides sustenance to each individual because his kindness is eternal.
