first time chicken mom and we have 7 barred rock pullets. They are somewhere around 16 weeks old ( maybe a bit older got them from TS). The girls are free range until they put themselves in the coup in the evening and I’m wondering what behavior I should look for. (We have one Roo is is starting to be aggressive and will be heading to cull soon) I have placed fake eggs in the nesting box for a few weeks to get them ready hoping they lay in the boxes and not in the yard. They have started digging wholes to lay in during the day all over the place. One under the RV one under the steps and some under trees . Lol Any advice would be great ! Thank you!
