starting out and appreciate different opinions

[dogman1 5]

can anyone give me some advice, i am getting a harris hawk soon and im needing some tips with the aviary. it will b an old dog kennel but it hasnt got any drainage and has a concrete base. i was planning on puttin astro turf on top of the concrete or pea gravel. are harris hawk casts toxic in any way or would they just wash into the ground with a good hose? i have experienced people helping me getting into the sport but i am going to b asking alot of questions on here aswell since i appreciate that everyone has different opinions and ideas. any pics of aviarys would also be very helpful. thanks for your time

pea gravel would be best, astro turf is harder to clean and in turn harbours bacteria. i use sand and sieve it, this leaves clean sand and a bucket full of excrement, pellets etc.

I use pea shingle mate just hose it down works for me
