I bought this to keep a sick chicken until she healed.  Appears that she was the loser in a hen fracas.  Nonetheless, it was wonderful to shuttle her back and forth from the vet.  She has healed nicely and is back with the flock.  I will keep it around for any other losers.  It also folds and cleans easily.  Several accesses.  You could also remove the tray to clean.
