I have a few questions, I just moved my girls into their coop and I have a few questions. First, what type of ground covering should I use for the coop? What type of ground covering should I put in the nesting box? My pullets are almost 7 weeks old, how long do I need to keep the light in the coop with them? (I am in Southern California, it has been in the 70's during the day and down to the 50's at night). Lastly, they are going to be laying hens, when do I need to switch them over from starter crumble to regular food? What type of regular food should I give them (crumble, mash, pellets?) There is just so much to learn. I thank you for sharing your wisdom!
