Causes of stunted chick growth?

That is promising news! She is still doing quite well, happily acting like she is no different than her friends! If my local store carries it, I may pick up the nutri-drench tomorrow- I am sure it will not hurt. May I ask, do you feed medicated or unmedicated? I have heard many opposing opinions and just want to give her the best possible start!

Great to hear! I've never fed medicated (this is my 5th batch) I'm currently using co-op chick starter and Kalmbach flock maker. I do put a bowl of dirt and fine grit from the yard in the brooder and give them finely chopped greens until mum takes them out then I just maintain food and water in the brooder until the chicks start roosting. Sounds like yours are of to a great start!
