She is a Black Star, about 7 mo old. Received all shots when I bought her. She can't stand today!

Some other board told me to give her milk, to build up her calcium. I gave it to her with a dropper. I think she aspirated some because she was wheezing afterwards, but I put tetracycline in the milk, thinking she could have acquired botulism. I went back to check her recently and she wasn't wheezing loudly anymore, but I still fear that some fluid may have landed in her lungs.

I have 2 chickens, they're pets. The second one is like nothing happened.

Any insights?
