Do baby chicks 'pee'? I just got 6 baby chicks from a feed store, about 4-5 days old. Their poos are sometimes runny, and sometimes they look like they're peeing. None of the ones at the above link matches what some of theirs looks like. Other stools are normal. They're on medicated feed, and electrolytes in their water. I'm thinking of cutting out the electrolytes after another day or so when they've settled down.
Chicken urine is white (urates) and it comes out kind of on top of the poo...mixed with it, so to speak. There should not be watery poo in chickens- that is diarrhea (unless it is a very hot day and they are guzzling water or you have fed them lots of fruit).
There is a caecal poo about every 8 poos (normal), that is runny but not watery...see the poo page:

So if they are having watery poo at that age you may consider coccidiosis, but this comes from soil. So there would need to have been soil organisms transferred into the brooder by your hands etc.
Here are signs so you can monitor for them:
lethargic
won't eat or drink
stands in corner by himself
feathers fluffed up as if cold
eyes closed
bloody or plain diarrhea
death can occur within 24 hours...it is emergency
I treat with Corid (amprolium) 9.6% solution, 9.5 ml per gallon of drinking water, mixing new solution daily, for 5 days. It is in the cattle section of the feed store and is approved for poultry but not labeled for poultry on the label. In the medicated feed, there is such a tiny amount of anti-coccidial medicine that it may not prevent it.
So, if they were my chicks and were truly having watery poo they would be on Corid. I have had quite the problem with coccidiosis here and it definitely can occur in the brooder with no contact with soil with transfer of the cocci into the brooder on equipment/hands.
