I learned a hard lesson this winter- don't hatch late in the summer and keep grow out into winter. Right now I have 2 roosters and 4 cockerels (4-6 months old). I have resorted to putting them outside, I shovel an area for them and have an extra large igloo dog house with straw for day time then let them at dusk, they were really harass the girls. It funny when they are outside and away from the girls they are a tight knit group with no bickering.What do you do with the boys who are picked on? I can't stand watching it.
The red pyle is my favorite but he's got a real attitude towards other chickens.
The Paint in my avatar is Monet, he had some real attitude towards me and my daughter from about 6-9 months old, he will be a year old next week and has really calmed down.
