Well.... I called the hubby and he was snickering at me. His suggestion was to keep our lil Roo until they both are bigger and if the hen integrates with the existing flock well and he's a PIA, then we will find him a new home then unless the feed store has some other option for me, I'll call and see what they have to say. If it's bring him back and get a tiny chick or my $3 back, he'll just stay and hopefully he'll be a kind, QUIET rooster!
My only guess is that raising our previous Roosters in the house until they were 5mo old wasn't a good idea. A well-meaning Kindergarten teacher sent my kid home with 2 fuzzy chicks in a box without asking me if it was ok, so I had no coop, no yard, no nothing for them.... just 2 chicks and a cardboard box! They ended up living in a bird cage and then in a big rabbit cage in the house until I finally conned my brother into building me a coop. Those Roosters, despite my kids taking them outside daily, were convinced they were house chickens and beyond mad that they now had to live outside.
