Hello --- I bought 6 Isa Brown chicks in early June, and successfully integrated them with my 3 RIR hens back in September (it was a little touch and go for a few days, but they all get along just fine now). Since they are just about 6 months old, it's about time for the hormones to kick in and to begin laying. Well, sure enough, yesterday when I went out to take care of them and gather the eggs from the RIR's, one of the new Isa Browns was sitting on the 3 RIR eggs (I'm sure they all came from the RIR's, I've been getting 3 a day for the past couple of months, very regular layers). Wow, this was one defensive chicken -- she was NOT going to let me get those eggs, no way, no how. I finally had to protect my hands with my sleeves and kind of "shoo, shoo" and physically push her from the box and shut the door to keep her out so I could gather the eggs. I just thought it was funny. I guess it might mean she would be a very good mother, except that I don't have and don't want roosters (I'm in the 'burbs, roosters would be too noisy), so she won't have the opportunity unless I slip some duck eggs under her or something. Now today, it was later in the day when I gathered eggs, and she was outside with the rest of the flock, so I didn't have this response. Does anyone else have an uber-defensive chicken like this?
