We were at Tractor Supply on May 7th 2016 and a nice lady gave me a hen and 3 chicks, She said they were bar rocks but the hen is fairly small. The bar rocks that I have had in the past were much bigger. The same day someone gave my husband 3 white chicks and we were told they were white leggings. The chicks looked to be the same age but the white ones were much bigger. They have been here just over 2 weeks so we can at least say they are all 2 weeks are more of age. The white chick has grown a nice wing span and feathers and yesterday I noticed tail feathers beginning to come in.What confuses me is the fact that the feathers on the wings are not all white. On the left wing there looks to be a couple of feathers that have black splotches but when the wing is extended it looks like the wing has feathers that have black and white stripes on them.That is the only color I see on the chick. Could this be some cross breed?
