While many people have their favorite breeds, I am especially fond of the Orpingtons (Black Australorps and Buff Orpingtons). Both of these are very friendly, great layers and over all a healthy sturdy breed. My Black Aussies are huge on lap sitting and just beg for the attention and lovin'. Excellent layers long into life.
Feel free to browse our forums, ask any questions you may have and good luck on this new chicken journey!!
I just wanted to echo sunflour’s advice on considering 3 or 4 to start with. I started with only 2 pullets and sadly, one passed away leaving one on her own. She was very sad and I had to dash out and find her a companion quickly; lucky I was able to do that. So yep, that buffer is an excellent idea.
