Can someone tell me what would be the best stuff to put on or coat my wooden roosts with??? I scrape off the roosts and sand them with a sander a couple of times a week to keep them as clean as I can but after 5 going on 6 years this is taking an awful toll on my roosts. I'm so afraid of giving bugs and illness a hand up so I work to keep things as clean as I can. I think I read ( here I think) about someone putting oil?? on there roosts. Did I dream that and if not what does that do exactly? what and how does it help? Is there anything else that might be better to preserve and protect the roosts as well as the girls??
