We ordered day old chicks 3 weeks ago. Everyone has been growing well at comparable rates until this last week. One of the Buff Orbingtons that has been growing slower all along (but still growing) only grew .2 ounces in 3 days. Some of the others, including the other Buffs are 2x her size! Most of them are growing .6-.8 per day now. The other concern is that she cherps loudly for long periods of time . She looks healthy, she is feathering out, stool is normal, she is eating and playing. Why has her growth slowed and why is she cherping (in a distressed voice)? I am a newbee and concerned about her and her affect on the flock. I appreciate any thoughts on this.
