I crossed over two varieties of same breed and ended up with a chocolate chick, which neither parent was chocolate, but would love to get these chicks to where they could breed true chocolate colors. What do I need to do with these chicks to get them to produce 100% chocolate chicks now? Should they breed true since they are chocolates or should I cross them back to parents for the next few years? The chocolate chicks will be laying this fall and need to know before they reach maturity on how I can keep these chocolates. Thank you so very much in advance
