Unfortunately, help is hit or miss on this site. Sometimes my threads get responses, but sometimes it's crickets chirping (always seems to be when I'm the most desperate for answers).
Can't really vote on this one, because my response doesn't fit into any of the options very well. I had one sick chick a few years back who I posted about - turned out she had wry neck. I did get some great advice, and she's still alive and thriving. However, I had an issue with her a few weeks ago and posted here, but got no response. Happy to say, she bounced back again.
In another case, I had an issue with a hatching chick... didn't get much help on my post. Sadly, I had to cull the baby chick and it was quite devastating for me. I hope to never have to do that again, but I know that I may need to at some point.
In all cases, I have updated my threads (even if no one responded) just in case someone else has a similar problem.
Raising chicks can be so hard at times - or, should I say, heartbreaking. You will have losses. Sometimes those losses will come no matter what you try. It won't be easy. You may even shed some tears. But, in the end, I've found the good has greatly outweighed all the bad. It's been so much fun and so incredibly rewarding!
I hope your sick chick makes a full recovery.
