I have three 2 month old Lorps, not sure of the sex of each yet but one is very agressive. "It" is developing faster and has thick legs. When outside of the coop, he attacks the others (2 other Lorps and 3 New Hampshire Reds) but is fairly calm in the coop and run. I will be looking for a new home for him as I want calm birds my grandchildren can handle and this one is not looking good.
