Whats best to put on the bottom of an aviary Rocks Bark chips Cement

My aviary just has dirt on the bottom & late today i noticed a mouse hole!!

What would be the best material to put in the bottom? Rocks? Cement etc.

Also, My bird ( galah ) never goes to the bottom of the cage, what is a good way to get her to do this?

Defintely Cement .. or use cement patio blocks if you do not want to deal with mixing cement.. also if you do mix it remove your bird while it cures until its dry..

A solid cement floor is best because its soooooooo easy to clean and disinfect.. also helps wear toe nails down on birds with nails,..

IF you are going to use the blocks..I recommend getting a package of little tykes blue playroom floor tiles.. they are a durable washable foam product. you can cut them to fit and place them over the patio blocks .. this eliminates the cracks between the cement blocks that will catch poop and food and be trouble to keep clean..

Also since they are washable you can take them out and disinfect put right back in.. nd just wipe off in between..

They also provide a cushon.. and the blue color will intrigue your bird and be calming.. Also not slippery if it gets wet. Easier on the feet than gravel.

The tiles come in packs of 4 tiles that fit together and cover about 16 sq ft for about 15-20.00 a pack. VERY durable..

I dont recommend any other brand than Little Tykes or Step Two. the other brands are not ok for all pets and also not as durable. we have a lot of experience with these tiles!
