You will find tons of nesting boxes at B&Q. I think they don't sell type of boxes these But I'm not really sure if they sell nesting boxes only for chicken.
Chicken nesting boxes are usually wooden boxes with some sort of soft padding that chickens like to roost in. If they don't have nesting boxes they will make nests all over the place in the grass.
you cant Try cover the nesting boxes in the evening before they go in to roost.
I have 24 and I have 6 nesting boxes. They share, and a lot of the time they wont even use one
Make laying boxes or nesting boxes for the hens to lay in. They should catch on to, and prefer the laying boxes on their own.
Depending on how much you are willing to spend, you may be better off trying your hand at building your own nesting boxes. However, if time is crucial and you have money to spare, some good vendors include Stromberg's Chickens and ChickenSaloon.com. Remember to give your chickens ample space!
Writing from experience I can say you don't "need" to but I would highly recommend it. putting some straw,hay, lawn clippings or another form of padding will reduce the number of eggs your chickens crack when getting in and out of the nest. Plan on your chickens laying their eggs in the most secluded nests if you aren't sure which ones they are pick the ones that are least convenient for you.
no
Always provide good nesting and laying boxes. If they continue to lay in strange places, it might take them awhile to figure out what the boxes are for. Try to set objects were they usually lay so they can't lay in that spot.
