I feel stupid even asking a poo question...

You are NOT being stupid. Chicken and especially their poo tends to be very varied, and still be normal. Here's the infamous poop page so you can see the differences.

remember there are no stupid questions, but there may be stupid answers...like mine.

 

There are two different types of poo that you will see. The 'normal' brown and white turd and then a brownish 'goo'. Both are completely normal.

Waste (faeces)
The remainder of the material consisting of waste and undigested food are mixed with the urine in the cloaca and eliminated from the body as faeces. The appearance of the faeces varies considerably, but typically is a rounded, brown to grey mass topped with a cap of white uric acid from the kidneys. The contents of the caeca are also discharged periodically as discrete masses of brown, glutinous material.
•The average daily production of faeces from laying hens is between 100 and 150 grams. These fresh droppings are approximately 75% water and will air dry under favourable conditions to approximately 30% water.
