I have 5 birds and everyone has been healthy and fine. Lately we’ve been having some colder wetter weather here in NJ. I noticed one of my bird had a spot near her beck where there are some feathers missing. Her face has also lightened a little in color and I think it just new feathers. I just picked her up and it seems like there’s dirt matted on her feathers. I checked all my other birds and only other other has a little bird on the feathers on her chest. She’s eating fine acting fine no weird poops or anything. Just wondering if I maybe I’m missing something or if I should be worried. Thanks.
