My LT Brahma just had a big, yellow, foamy poop. I did a search but didn't find anything helpful. I am sure I have read threads on this, but I just couldn't find them. From what I remember this means she has worms, right?
best to have a fecal test done to check for worms, and what kind.
if you are able to have a bacteria test done, that would be good.
do you have a worming med?
as to "SweetLilRachy00"...check all droppings for worms.
any possibility it's a maggot?
check mouths and throats ..
are the chicks in a brooder?
check feed (in brooder/feeder/waterer, and bag)
clean up any spilled or wet feed.
