Do I need bedding in a CS?
My brooder floor is 1/2" hardware cloth. You might be able to see it in this.
As you can see, the floor in my grow-out coop is also 1/2" hardware cloth.
The poop falls through until the chicks get maybe 12 to 14 weeks old, then the poop starts to build up. It gets too bit for the 1/2" holes. I have no experience with using 1" holes so not sure if those will ever clog up or not with adults.
If I'm keeping chicks in that brooder in winter where it gets cold, like below freezing, I put a piece of plywood on the brooder floor to keep the wind from hitting them underneath where the heat is and block off under that brooder so a breeze can't blow on them. Like this.
In the grow-out coop I just block off underneath with scrap aluminum to block wind, nothing on the wire. This is for winter. In summer it's a lot more open.
I figure pictures makes it a lot easier to understand what I'm talking about. As long as the weather is suitable I don't see the problem with the bottom being wire as far as the chicken's health.
I don't use bedding in ether of mine. There are no nests since they are not laying. I could see bedding being a problem.
One word of caution. Some, not all but some, wire mesh may have sharp spikes on it. That could come form the wire mesh manufacturing or from the galvanizing if it is hot dip galvanized. If they walk on those spikes it can tear their feet up. Due to the manufacturing process all those spikes (if they are any) should all be on the same side. So carefully rub your hand over the side that is up and see if you need to do any rearranging. If they point down it's not a big deal. They are not walking on them.
