My 13 year old son enjoys raising black sex link chickens. He currently has 8 hens that are a little old for his liking. He told me the other day that he wanted some new chicks so he start start fresh with his flock, so he asked me to call my friend to see if he would buy his old hens. My friend said he would, but my son has chnged his mind twice!!! Now my friend is on his way to pick them up....should my son hold up his end of the bargain or be allowed to change his mind. I say he should sell them since he made an agreement. Any suggestions?!!
