Anyone know whats wrong with my quail? HELP ASAP!

I have a 6 month old coturnix quail, she is in a cage with one male.

She's been acting weird the past couple of days, just sitting in the corner, sleeping all day, like she's sick. She doesn't even really move around to much.

She is eating and drinking, I gave her some boiled egg today. but I'm getting really worried.

She laid a brown egg the other day (if that makes any difference) but she seemed like she was sick that day and she still is acting weird.

Anyone know what it could be or anything I could do to help

ALSO*** I left their cage outside in 65 (maybe a little warmer) weather. (she's inside right now) Could that have done it? does the cold really affect them?


HELP PLEASE, I'm afraid i'm going to wake up one morning and find her dead.
