We just bought a White Plymouth Rock from a feed store. The store says she is 4 months old, but she looks more like 2-3 months to us. She has very little crown and still sounds like a chick with an occasional almost-bock when she is scared. As far as we know she has spent her entire time in a cage. She seems to be affraid of heights and uneven surfaces and really cannot fly at all. She is very friendly but lacks balance and is a littly shy of exploring. The food we saw them feeding her at the store looked like it was just cracked corn. Her claw strength is good but her balance is bad. We are wondering....will she grow out of this? Is it due to being in the cage? What about her limited diet? Currently she is getting chick crumble and allowed to free range with our other big girls in the backyard, but she stays very close to us. Any information appreciated. BTW, her name is Ice Cream and we think she is very sweet.
