nest box advise

I would split them, but then others may say the opposite, my way of thinking is when chooks lay they like privacy and to be snug.
I have two boxes but they only lay in one, always have and I suspect always will.

Separating the nest boxes makes easy cleaning and gives the hens a choice of where to lay.

Personally I'd section them off.

\i have to agree with all the above

I think the books recommend that you have 1 nest box per 3 chooks.  However, I think the chooks might have access to a different set of books, cos they tend to have a fav box, and will all go in the same one, unless it's already occupied, then they'll move on to the next one.

So, depends how many chooks you have.

I have 3 chicks and 2 nest boxes and they all used to take turns each in different boxes, but since Grace has decided to go broody she will not move out of her favorite box.  The other two just pile in on top of her and insist on laying there, both at the same time.  Makes it difficult to do anything about the broody as it's always when I am leaving for work, so wee Gracie is nice and cosy nesting on the other 2's eggs all day.  Boy is she in for a shock!!! Have 3 days off coming up and she is going to be kicked out of box as soon as others have laid. Hopefully that will put her off.       

Good Luck - we needed a pair of up to elbow pruning gloves to get our sussex out

Haa!  Can just imagine the scene.   Bet she was cross.
