Tiffany, Actually these are concrete floors. Converted carport space at the "crazy bird house'. Those are cypress mulch pieces. The big live Pittaspora plants and spider plants had a thick layer of mulch on top of the dirt to keep the birds out of the dirt. Those crazy Zebras tried to carry the pieces around looking for a place to build a nest....lol..they were funny to watch. Some could carry pieces bigger than themselves... most ended up on the floor. I just haven't swept yet.
Normally in the summer I use the shop vac and then blast with the hose. I also ocaisionally spray pool chlorine on the concrete when it is empty. I will not wet it for the entire winter...just sweeping and vacuuming. The plastic cover makes it take way to long to dry and I don't want a mold/mildew problem. I have to open the front and back doors during the day, It will reach 95% in there no problem once the sun is up. The day time temps have been in the mid 70's lately and 50's at night. On cool mornings I simply open the door and let all the heat go up the stairs to the indoor aviaries. I am going to plastic the balcony aviary this weekend and putting thick linoleum on the decking to cover the crack. I won't be keeping birds out there for the winter as it is facing north. Lot's of cold north winds blow across the lagoon there. But the plasticing should insulate the room I have my gouldians growing out in. The other morning the glass doors were bery cool, The birds were comfy as I have a heater in there but I don't want to spend a fortune on electric bills so I am capturing the sun's heat
This is the balcony and the gould chicks project.
Chilly Chicks ... the room to the right is the redheads colony. (chicks in nest already) They love sitting in front of the sliding glass doors and look out.

I will plastic the inside of the wire..... no ladder in the sand for me
I will cover the cracks. This will not only keep wind/cold out but the mosquitoes nest spring
