My 8 month old crested cream behaves differently than the others. She has had poopy butt problems for months now. I have noticed when she breathes her throats goes in and out, as if she's exherted, but she breathes like that all the time. Sometimes I hear a clicking noise when she's breathing. When I listened to her chest, there is a "squash, squash" noise instead of a normal strong heartbeat. She always seems more tired than the rest, although yesterday I saw her run to catch up with the others. She is the youngest, so for a while I've believed she is just a bit behind. But now I'm getting concerned. She acts as if she wants to lay, but has not yet laid,an egg. This has been going on for about 2 months. No one else is behaving this way. Any advise, suggestions, etc. would be appreciated. Thank you. I tried posting a video of her breathing, but have been unable to upload it.
