I don't mind it myself I just want to know if they are stressed about something. That may be keeping them from laying.
They may just be getting ready to lay??? My Chocolate Orpington did this right before she started laying. Around 11am each day for about 4 days. Then she layed her first egg and didn't make a peep! Hilariously backwards! LOL She has days where she sings her "I layed an egg" song and other days she just hops quietly down from the nest box having only made a grunting sound while the egg was coming out. Go figure!
