I have a rhode island red rooster, he is with red stars, tetra tints, leghorns, and Dominique's. What would the offspring be if he bred to these ladies? Look like? Good layers? Name for the crosses? Thank you in advance. (Only asking because I have a cochin bantam who went broody, and was wondering if I should put any of the fertile larger breed eggs under her, as I would just keep the offspring as pets).
