I am new to this site, and I have searched to see if anyone else has had the same issue as me, but to no avail. So here is my problem: I bought 6 chicks 2 weeks ago (2 buff opringtons, 2 RIR & 2 unknown w/black feathers). Up until today they have been great. This morning when I went to change out their food and water one of the buffs acted very aggressive. She flew at the brooder door (it's a re-purposed wire dog kennel) when she saw me and bounced off. When I opened it she charged at my hand and started pecking at it like she was trying to get me to go away. After I washed their water and food dishes I went to put them back in the brooder and again and the same chick lowered her head a bit, and proceeded to charged at the door once again and bounced off, and once I opened it she actually chest bumped the water container out of my hand and proceeded to start pecking at me again. She almost acts like she is trying to protect the others and keep me away. Is this normal behavior? And if not, what can I do? My 18 year old son is now refusing to even help out with them because she acts like such a jerk! I don't want to do something wrong and make it worse, so any suggestions would be very welcome!!
