I'm one week into my first four chicks. So far so good. But today my Brahma is doing this weird thing where she stretches her neck upwards and opens her beak like she's going to chirp but nothing comes out. I'm starting to worry. I can't tell if she's struggling to swallow something or having trouble breathing or trying to chirp but mute. No clue. She's a bit lower energy than the rest today too. What should I do? Thanks!
