I would wait a day or two before removing them. I had other chickens that would jump in with the broody and lay an egg than leave, so you end up having some eggs that aren't 21 days old yet. It happened to me.
I have an Australian Shepard that is 8 months old and he started out trying to herd chickens and I didn't think I was ever going to break him of it but the best thing to do his keeping taking your dog down when you do chores and keep an eye on him and eventually the newness will wear off and...
I can't wait to hear more on this topic, I have an 8 month old Aussie and he wants to herd them and of course you know what a chicken's reaction is to that!
Where my perches are located I fenced around underneath it so they can't get all through it. It's on hinges and I just lift it up and clean it out and put it on the compost pile.
I was wondering what an average egg weighed. I just went to the post office and they weighed one for me that was 3.9 oz. It's been cold here in Milo, ME. It was 28 below here last Friday nite. Thanks
