Our one year old Light Brahma roo has always been very gentle and never aggressive. The last week or two he has been charging and pecking all of us in the family. We all spend time with the birds and we raised him from a day old. The only new thing is that there is a month old chick in the flock--the only of a broody silkie's babies to hatch. As the weather has warmed up, they have all been outside in the yard. Neither he or any of the other hens has ever been aggressive towards the baby, so she seems to be very well accepted. Could his orneriness be caused by an urge to protect the little one? We are dumbfounded. He's always been such a good boy.
