On 8/22 I received an order of 7 guinea keets. One really small pearl and six whites. All went well until three days ago when they started dropping like flies. I've successfully raised keets before with zero losses, but those were from a breeder and these are my first hatchery keets. I got them from Ideal. The temp in the brooder was right on 95 the whole time and they had plenty of space to get out of the heat. Same unmedicated chick starter as the last batch. Water is changed daily. No shavings or any non edibles for them to eat. They never appeared stressed or in distress. Other than the small pearl they all grew nicely. Starting three days ago I found one dead per day. They'd be fine in the morning and dead by afternoon. No disharge anywhere, eating and drinking fine, good poo, and then dead. Just like someone had hit an off switch. They are kept in the house away from other birds and have not even been on the floor. They all arrived perky and healthy. Does this sound like a genetics thing?
