I've had these chicks for about a month now, with a Buff Laced Polish, Blue Andalusian, and black silkies. Everyone is well-fed, watered, and all,but I'm sort of worried about one of the silkies! She has a stuffy nose and is acting somewhat frail, but she acts a lot like the other chicks and runs up to the cage when she sees me, so I'm confused. I've been noticing it for about a week, but no one else has it. Her poop is fine. Does anyone know if this is just allergies (we have a high pollen level), getting cold (the place I am keeping them seems a bit chilly), or if this is an illness? Thanks to everyone who helps!
