Silkies are wonderful aren't they! Though I'd be careful with what you feed your chickens, especially leftovers. Carbs are better in moderation if at all and salt and any spices you would put on something for a human to eat will kill a chicken. Foods containing large amounts of salt can lead to a condition known as salt poisoning, salt toxicity, hypernatremia, or water deprivation-sodium ion intoxication. The small bodies of chickens are not meant to ingest large amounts of salt.They will eat whatever you give them and it is up to us as the owners to keep them in good health.
