I have new chicks. Sad to say something took one from me this morning. I am not sure now what to say that she had. I am thinking now that they have worms or internal parasites. I want to try and treat for both. What do you suggest I use? I have that D Earth stuff the food grade to mix in the food. Is that enough of do I need to add something else? The poop is yellow and foamy but symptoms are sneezing and snot bubbles. But one died this moring and I want to make sure I dont lose any more
