I will say that while he may love his "bio" daddy it's still really tough to be in this situation. Maybe he needs some counseling to work through his "issues?" with this it may help him out. I am a firm believer in a good counselor. Maybe he can work it out now and not when he's older. Good luck with him.
Also get him to clean up any mess with you but quietly, dont yell give him some cleaning up stuff to help you do it,
This is a tough one isnt it,he is however telling you something and you need to listen to it, he is asking for more attention, possibly his brothers get more Has he got his Dad or step dad to play sports and Games with him just the two of them not the others, he is acting out as he feels sad,Spanking doesnt help it reinforces negative patterns he will copy.If things got too desperate and he loves his Biological Dad could he go there more, Very often kids will seek attention through negative ways . Try quietly asking him Why he thinks he does these things , no yelling just gentleness and Hugs .
