I have osb on the upper part of my coop. I am a painting contractor and believe me with all the paint we have left over from customers it is easy for us to use. I have painted my coop 3 times inside already and we have never had a problem with the chickens or the wood. If u use a good gloss finish on your floors you will be fine. It's easy to clean. Just make sure when u paint it that you get all the nooks and crannies that osb has. Latex paint will not harm the chickens. I did paint the underside of my coop floors as well just for precautionary measures because we did not use pressure treated wood as this is def toxic to chickens. Using poop bards under the roost helps with the moisture on the floors as well. I hope this helps a little
