Hi guys! I need some urgent help ASAP! So my 9 month old Australorp has been brooding for about a week now and I just did my usual rounds to go pick her up and move her and she has like brown/yellow mucus that seems to be more thick than think draining from her nose. There was also some dried up on her nose that was white. Research I've done tells me that this can be dangerous and I want to get this taken care of ASAP so I don't lose any of my babies! Please help!!! Thank you! How do I take care of it, and what is it?
