Nesting box problem, stubborn hens

We have a large (2'x4') community nest box on the floor of the coop. 3 of 16 hens like to lay in there, -it is dark and private.

Earlier this winter, we had a problem with a white leghorn pullet laying her eggs off the roost at night, resulting in broken, frozen, or at least dirty eggs. We put a nest box up on the poop boards in hopes she would use it if she had the need to lay an egg at night. It seems to have worked, - she uses this "poop board box", and while it could be coincidence, the night laying stopped.

The problem: 12 other hens INSIST on using this single box, and that box ONLY. There are fights every day, sometimes with blood drawn. I am thinking about taking the poop-board box away entirely, or at least setting it on the floor by the community box.

My question: If I suddenly take this box away, am I setting myself up for chaos (eggs laid all over the floor, poop boards, etc) ? As a first attempt at a solution, I did try putting a similar single box, elevated about a foot off the floor, over next to the community box, and no one will use it. I put wooden eggs in it, and they do get in it and check it out, but when it is time to lay, they head up onto the poop board to fight with whatever hen happens to be in that box. It is rare that 2 hens peacefully share the space. Should I take it away?

I appreciate any advice!

 

Thanks for the replies. I'm glad to hear that I'm not the only one with hens that draw blood over nesting boxes!

I decided to go for it and move the box. Right now, next to the community box on the floor, I've put a large cat carrier (maybe a foot wide and two feet deep), on top of that is the formerly favorite box that came off the poop board, and on top of that is another single box that they previously refused to use. DH screwed them to the wall, so they won't topple. They all have fresh shavings and fake eggs.

In addition, they have a small community box that is hung under the poop boards. It has been there for a long time and no one uses it, -it isn't very deep, but it is certainly another option.

I'll be very interested to see what happens tomorrow!

 

Success! After much loud whining about the moved nest box (I swear the Brahma is going to be hoarse!), the hens have laid in 3 different locations today. No one has used the "pet taxi" box yet, although they moved the wooden eggs around in there. I'm hoping this settles the major fighting at laying time long-term!
