I received 6 BCM may 29thish that I was told were just hatched the day before, along with a mix of BCM, Blue Marans and one Splash that I was told were all a couple weeks old. 3 of the little ones have hardly grown at all and still look like baby chics. The other 3 are hard to tell apart from the other bigger ones. They are eating well and drinking. I switched the little ones back to medicated chic feed just to make sure they are getting everything they need. Is this typical, should I write them off or wait it out. Thanks for any advise.
