Chicks come in pairs

 
When we got to hold and take a good look at the chicks we realized that the chicks come in pairs!  Two of them have light brown, another two dark brown.  Two of them are gray and the other two speckled gray.  I took some pictures of the chicks with their pair.

The chicks above are the light brown ones.

These chicks are the speckled gray ones.
