I have been feeding my 9 week old chicks avocado (it's in season and we're overrun with them) and they seemed to love it. Now, today, I've been told it's actually poisonous! Do I need to do anything? They seem OK. One young roo seemed a bit lethargic yesterday, but I assumed it was just feeling sorry for itself after a beating from the top rooster (he had a bit of his comb ripped, poor thing). All are eating and drinking. .... The sad roo is eating when the others are away from the food bowl, and doesn't seem overly enthusiastic about it. Help??
