Three of my girls are of egg laying age and are showing all the basic signs of being ready (comb and waffles are getting red, squat when you approach and pet them). My question is how do I know if they payed their first egg if they are not in their hen house?? (My girls free range through your my backyard almost all day. Usually 11-12 till it gets dark and they go in the hen house on their own, I check on them from time to time to make sure all are ok and bring them Treats here and there) if one of them is ready to lay the first egg and they are not in the house is there a way for me to know or am I gonna be doing an egg hunt daily??
