Metal Tray Rusted, What To Use To Seal, Repair or Replace

[VintageLilFarm]

I have a Summerhawk Ranch coop for an extra coop for birds I want to keep separate. I have just cleaned it thoroughly in prep for moving my chicks into it. The metal tray that slides in to catch poo is rusted. We have removed what rust we can with sanding and rust remover, and we'd like to seal it and/or do something to keep it from rusting again and also to provide a barrier so if the chicks scratch at it, they won't be getting rust. I have a spray urethane product. I know there are rustoleum spray products out there also, that are made for this. I just want to investigate the safety of using those products for this purpose. We are also wondering if we should just take that metal piece out and replace it, but would rather not!

It will be mostly covered with pellets or shavings, but you know how they scratch around! Any advice would be appreciated!

Any paint product will protect it. (nothing is for ever) You may consider some contact paper placed on pan bottom.

Yes, I can figure out products to protect it. I'm concerned about the safety of my chicks coming in contact with whatever we use. So wondering what would be best, given that chicks will likely scratch at it.

I would go with sticking the contact paper to the tray surface. No concerns with that getting shredded or eaten at all. When it starts looking shabby, then replace with new sheet.
