Well, maybe two weeks. The middle of last week I went to collect eggs and only had 3 instead of 12. Then the culprit slithered out of the coop! I have yet to catch that snake back in there and it is still getting my eggs. Then I moved some of my older babies out of the brooder into the nursery pen, b/c we are seeing 80-90 degree weather and I figured they would be more comfortable. I left my guinea keets in one side of the brooder and my quail babies in the other. With a thermostat, so if it got too cool the light would come on, but otherwise stay off. I went out Sunday to show off my babies to a friend and my half of my guineas were dead and the other half staggering as were a few of my chicks in the nursery pen. I freaked and did fresh water, fresh food, antibiotics and vit/electrolytes. Yesterday I went to check and the rest were dead. And I lost a few of the chicks in my nursery pen. But only the ones that were visibly sick the day before. Today I went out and almost all of my quail are dead, the rest are sick. I don't know what it could be, or what to do, it's just all of a sudden. The day before they are sick, they are running around just fine, then BAM! I am sooo scared that tomorrow my whole nursery pen will be wiped out. Someone mentioned it could be the heat, but I don't really see that. I may be wrong though. Any ideas???
