is this sour crop? a clear liquid kind of trickles out her beak and when i press on her crop a whole bunch comes out. her eyes are clear, but she has been staying in the nest box for a while. at first i thought she was going broody, but i'm not so sure now. she still tucks eggs under her though, so this is a good sign, right? i've put her in a seperate cage with fresh water and some dry bread. is there anything else i can do for her? i really don't want her to die as her sister passed away only last year and her father isn't looking too good either, so if you have any advice or experience with this please let me know. thank you in advance.
