I found a bump near my 2 month old Australorp's nostril and I'm trying to figure out what it is. I noticed it last night when I was putting her in the coop for the night and it wasn't there yesterday morning. It doesn't look like an injury. She is in a large run with 2 other chicks same age (lavender orpington and silver laced wyandotte). The run is separated by hardware cloth to integrate them into the flock of 3 older hens (buff orpingtons). Bedding is sand in the run and the coop has Aspen. No other symptoms and everyone is fine. I just wanted to catch this early in case it's something that needs to be treated. I hope these pictures are ok let me know and I can take more
