Can't catch a break this week. Went out this morning and made sure water (using nipple system) and food were full for the 4 week old birds (to be fair, there are a couple in there that are older, but they are d'Uccles, so they will soon be dwarfed by the bantam cochins and the bantam cornish they are sharing the "big kid brooder" with.). Everyone was looking chipper and good. Didn't have time to handle them all, but figured if they all perked up their heads when I looked in the top they were doing great. Came home from work 10 hours later, not quite through all the food and made a good dent in the water for the day and my bantam barred cochin cockerel was dead. He was not by any means the smallest bird in there and there have been no signs of cocci. Checked temps and there is a nice warm spot under the lamp with ample room to move away from the heat. Wondering if maybe he decided to sleep on the bottom of the chicken pile (they were chicken piled up when I got home) and suffocated. I have only had that happen in the first week before when I've had very small bantams in with slightly larger bantams, sometimes of a slightly older hatch. He's not a particularly fast growing breed, so I don't think it was likely heart attack. And he was in warm spot, so very unlikely that he got too cold (though I did adjust a couple things cause I did notice there was a particularly cold portion of the brooder). Oh well - he was a free chick anyways. (we ended up with so much loss on our Welp order earlier this year after they were lost in the mail that they are re-doing the whole thing). Just sad cause I ended up lucky with 2 pullets and a cockerel which would have been a great start to breeding that variety and cause I never ever am not sad when a chick or a full grown chicken passes away, regardless of reason.
