I recently bought two baby chicks and the first day they seemed pretty active and good until today one of them just kept standing up and going to sleep rocking back and forth, she does not wants to eat or drink, she does not poop either well just two times in the day and very little, her poop is white with just a pinch of brown, I already check her for pasting and she seems fine, she is just very lethargic and always sleeping. What can I do? Is she sick or just lazy? Help!!!!!
