I think it will be fine as long as it rests and stays warm for awhile....mine were worn out like this also...but the next day they were up and running around....YOU DID A GREAT JOB!!!!!
You did a superb job helping that beautiful chickadoodle outta there! Without help, a chick who pips the wrong end would die in the shell from exhaustion. I have every confidence that that chick will thrive in your care. The hard part is over. Congratulations!
