I bought some day old chicks for my kids and have raised them for about 9 weeks now. We also rescued 2 older chooks from some friends who wanted to get rid of them. The 2 older chooks are laying eggs but they are laying them on the floor of their coop and then standing on them and breaking them. I have tried using old milk cartons as laying boxes and puting hay in the bottom of the milk cartons for them to nest in. But when I go to get the eggs that have emptied the milk cartons because they have gone scratching in the hay. Also is there a certain time of day or night they lay and does the laying boxes need to be in a dark spot for them to lay? This is all new to me so any info would be great.
