Many of you know that we had a sick cockerel. We are sure it was a mold issue and not contagious for several reasons.
First, this happened last time it got cold/wet and he never really got 100% after that. Always made odd noises and didn't crow right. No other symptoms. Eventually we took him out of isolation because he didn't act sick except for the weird noises. He ran with the other birds for about 6 weeks and none of them so much as sneezed.
That's reason number 2. Had the cockerels condition been contagious, I think we'd be dealing with more sick birds. Before he was found, he was badly sick for 2 or 3 days this time. Due to all of our out-of-state family, the children (often with cousins along) were doing chores. They do a good job but don't/can't equal an adult. When I found the cockerel, his comb and wattles were already blue from lack of O2, he'd been sick a good while.
Reason number 3 is that I was discussing Ron's post last night about black mold in straw. My son over heard the discussion and piped up (I have been very careful not to cast stones - it's a big burden for a boy) saying he had put some moldy straw in the hen house a couple weeks ago. The straw has since been replaced with fresh but the moldy straw could have generated the problem with the cockerel.
We obviously have a lot of learning and educating to do around here. We lost a friend due to combined ignorance and genetic weakness (none of the other birds got sick). I'm just glad it doesn't appear to be contagious.
My poor husband said he knew how it felt to shoot Old Yeller now.![]()
Some things we've learned have been regarding what is necessary in a medicine cabinet for chickens. Mine is sadly lacking and we are remedying that straight-way. The other thing we've learned has been in regard to mold and educating our children. WE (adults) knew that the straw had got wet and was no good but it hadn't been disposed of so it got used while we were busy. We are having to rethink our methods and may go to sand in the winter, I don't know yet.
The stocked medicine cabinet is a big deal because so many really good products are only purchasable online.
I'm so sorry you had to put him down.

I'm so proud of your son for speaking up about the moldy straw. Some kids would not, thinking they were going to get in trouble. And this will be a learning experience for all of you. And you will now have a well stocked medicine chest! Since it didn't seem to affect the others, it may be that he did not have good resistance and the others did.
