I am a newbie to raising chickens. We bought week old chicks from a few different places. I have a couple of each ~ silkies, frizzles, new hampshire, amerucana, barred plymouth rock, wyandottes, a black australorp, a light brahama and a orington. The first batch we bought as a straight run, so I'm sure I have a roo or two. I love them all, and are hoping that most are girls. (I don't want to part with any!) I enjoy watching them, and can't wait for them to grow (which is at a rapid rate I see ) They are 4-6 weeks old , except for our new lil Rhode Island Red thats 2 weeks. We watch them alot. Coffee every morning and iced tea every afternoon ~ evening. They get along great. No pecking each other, and the little RIR is happy and content. They are in a large enough space to roam. We made a chick pen on our back yard grass with old Rack shelving stacked behind the grocery store that they were tossing. We stood them up on the sides and zip tied them all together, and made a roof the same way~ leaving one corner zip tied on one end so we can open it up to get in. We also covered the roof with a roll of bamboo (doubled over) I add a king sized fitted sheet at night over the whole thing & turn the lamp on) Works Awesome! Okay... Now my question. Will the mixed breeds get along if they are raised together or are they going to get agressive. I bought " Keeping Chickens" book and it seems to tend towards no? I've been reading alot of posts here and think it's the best place for info. Love this site! Thank you!!
