Sometime last night, my favorite Japanese coturnix quail passed. She was lethargic for the past few days, but she seemed really bad last night. I thought she was egg bound, but I've never experienced it before. I just got this based off of watching videos and reading posts/articles online. Her breathing was labored, she was fluffed up, her eyes kept closing, and she wasn't eating or drinking. I tried putting her in a warm bath before I went to sleep, but she was gone when I woke up. I have two questions that hopefully the community can assist with: 1) Does anyone have any ideas on what happened to my quail? 2) The cage mate has been crying all morning and keeps walking around the cage looking for her friend. It almost sounds like a loud cricket / sonar sound. Anyway, has anyone successfully added a new quail to a cage? She's a female and was with the female that passed. I wanted to note that I have them for pets, not for breeding. I initially got these 2 quail in hopes of adding them to a male/female cage, but they (the male/female pair) attacked the new girls. I immediately separated them and kept the new girls in a separate cage. I'm scared to get another quail in the event the lone female doesn't like her. Would it work to just keep her in a cage next to the other cage (so they can see each other)? I also have a cage of buttons. Any ideas or recommendations?
