Ok, if human mistakes have to have it, how bout this?
When I was a newbie, I had wanted chickens so bad, but didnt have a heat lamp or even anything that would work as such, but brought them home from the feed store anyhow.
We keep our house warm in the winter/spring, but not quite THAT warm, so I put them in a box on the stove with the hood light on. Well, they were plenty warm, but I had a rag in there for them to snuggle in.
I had one that just wouldnt settle down and cried and leaped around. I think she was a little older than just 2 or 3 days, and she had never been in with the other two before, they had been in separate bins, so she FELT alone I guess. Cried her little heart out.
Well I underestimated how high she could jump. I nursed her for several hours, put her back in the box, went into the bathroom, hear a ruckus. She had jumped out of the box, and fell all the way down from the stove, and hurt herself pretty badly. I think she dislocated her wing, and hurt her foot. I still carry guilt for that one but luckily I dont think she broke anything, I was lucky in that respect. The other two slept away this whole time...snuggled in the corner of the box, so she wasnt cold, just scared.
She is ok, but to this day doesnt like heights of more than about 18 inches. And I have to put her down carefully, her foot still aches if she jumps too hard, and her wing pops out of place occasionally. sigh....
So, yea...I know what you mean...I wasnt sure she was gonna make it there for a while....
