I have 3 RIR mixed? 25 wks 1 has been squatting for 2 wks tomorrow and a few times has dug around in the nest box moving golf balls and fashioning a nest. Well yesterday and today around 8:30-9:00 AM she has been in coop BAAK BAAK BAAK BUH GAWK really loud and crazy for about 1/2 hour or so on both days. I was excited yesterday went out and NO egg.... Today same thing except I was convinced this was it! I even took my camera out to the coop and again NO egg.. Is she rehearsing for the real thing or what? Is this normal and if so how long on average will she rehearse?
