Help, my chickens just ate something with nutmeg

[DianeB]

I was stupid enough to give two of my hens a taste of a dish with nutmeg. Forgot that is on the very toxic list for dogs, cats and birds. The whole dish (8X12 pan) had about 1/2-1 teaspoon of nutmeg. They only had a 1/2 -1/4 tsp. of this entire dish. Will it effect them? It is suppose to cause seisures.
