Growing up I had 3 hens that started out as Easter chicks. Well, 2 of the 3 decided they would venture over our 6 foot privacy fence into the neighbors yard. Unfortunately, green grass and bugs weren't the only ones waiting on the other side, their Doberman had a grand ol' time eating and mauling my Barred Rocks. The 3rd hen, a Rhode Island Red, must have realized there was a reason the 2 Barred Rocks never came back, becuase she never jumped our backyard fence. LOL
I had always used newspaper as well, that is until I had a whole batch of chicks go splay legged. It was aweful, we weren't able to correct any of their legs, they all died. If you use newspaper just be sure the use the black and white parts, as those have more texture and grip. Do not use the glossy colored advertisement papers because those are much more slick and are that mush harder to walk on.
I started using shaving, got the large bag of shaving at
Walmart. They are great, I'll never use newspaper again. The shaving absorb the poo, gives them something to snuggle in and it cleans up better than paper. Because it absorbs the moisture out of the poo, the poo doesn't stick to the chicks, brooder, waterer, feeder, or even you as you clean it. LOL All you do with shavings is pour out the whole batch and then put a new layer in. With paper, you'll peel it out but all the moisture and poo is still sitting on the bottom of the brooder. I can personally tell you shavings are really the way to go.
