I got a new quail that is 3 months old. We have 43 total quail. She was vent checked, but she is crowing every once in a while. I have vent checked her several times since out of confusion and still a female! No bulb and no foam. What the heck?! All of my others are super obvious. Any ideas?
I’m not trying to make assumptions about your vent sexing skills but are you pressing? At this age foam should be present so... Update us!
