I have 4 coturnix quail ( adults ) one of my females I have noticed has a very large crop - feels like a squishy water balloon. they are inside in a cage that is 48 X 24 - they are fed 30% protein quail food along with other treats like cooked rice -- corn -- and I grow grass in swallow dishes and when it " needs to be mowed " I let them have it for the day along with food and treats they have fresh water should I remove the food at night to let her crop go down ? I have felt the crop area and I can not feel anything in it ( other than the squishy feeling ) it does not feel like there is anything impacting her crop. she is still very active eating - drinking - running around - mating - and lays an egg a day ( I think she is my double yolk layer ) culling her is NOT something I want to do since I only have 1 male and 3 females. so any advice to offer ?
