i have 3 br hens and see 5 eggs in a nest today. however, she is not sitting on them. will she continue laying until she has a clutch and then start sitting on them?? or will these 5 go bad from not being kept warm? also, if she starts sitting on them how many days before they should hatch out? i assume if all goes well i should just put some starter in for the babies and hope the grown ones dont eat it all. they are in a very large area so i am hoping they will be fine. the exercise yard area is 21x35 and the sheltered area is probably 45wide, 30 deep and 20 high. thanks for any input.
