Are you using pop bottle PLASTIC waterers? I don't think that is a real bonnet crest. Looks like she is wearing off the middle. The tape goes all the way around the base of the crest, and makes it stand up, not flop.The tape will protect the middle of the crest too.
Look for WHITE kitty litter. I put 2" sides around my show coops, and kept all my birds on it. You must clean feet and vents every day, and scoop the litter. KL does not stain foot feathering like shavings do, as it has no oil. It draws oil and moisture out of the feathers on the feet, and prevents staining and clumping, which destroys foot feathering.
