We ave two chickens - penny we have had about 3 weeks, Henny for almost 2. We think Henny is older (she has a deep voice and is a grumpy thing lol) and penny is probably a year, maybe? We don't know the origins of either. They are both isa browns. Penny started laying a few days before we got Henny, and has been consistent. One day penny didn't lay an egg. I wasn't worried, but wondered why. She has cute little speckled eggs. The day after penny didn't lay, we found an egg in henrietta's cage aswell as penny's cage. The one in henny's cage looked different (it was perfectly coloured - completely brown, but still about the same size as penny's (44g) ). Do you think henrietta layed it? They do have access to each others houses, but I foud this egg right in front of the door of henny's coop and it wasn't there when I locked her in. (Could she have rolled it to the door if it was penny's? ) We have now put them both in together - which s going well... Then a couple of days ago I got a 60g egg from one of them! Again it was darker brown and not speckled. Yesterday the egg I got was still reasonably large, but a bit elongated. And now today, the egg is stripey (see picture). Can anyone who knows something about eggs shed some light? Do they normally lay the same coloured/size eggs every day, or does it really differ from day to day?
