About a month back i purchased 13 roughly 4 week old quail. I have them housed in a hutch with a run on the ground, they love dust bathing and everything. But as of the last 2 weeks or so. Every now and then they will go ballistic when i come near. All running around the pen frantically. A few jumping and hitting their heads on the wire roof. Just now though as i went out to the hutch, i saw some pigeons, which flew away as i approached. The quail were fine at that point. I opened up the hutch and noticed an egg, off time from my usual egg so i believe we have a second layer. It was about the time i went to retrieve the egg that all of them went crazy (We have no males so it's not a fertile egg) They ran around but even more so this time, crawling over each other. Heaps of them jumping up and hitting their heads. I tried replacing their food with new food. And cleaning out their water and hutch bedding. They didn't calm down for a long time. I do not know what is wrong with them or why they seem so suicidal. Would anyone be able to give advice for calming quails or any ideas as to what it may be?
