I have 5 new chicks; 4 of which started laying. RIR @ 18 wks, Ameraucanas (1 @ 20 wks and 1 @ 21 1/2 wks), 1 Buff Orpington @ 20 wks. They are 24 wks today and the other buff hasn't laid an egg yet. Any insight on why she might be so late? She is supposedly born at the same time (within a couple of days) of the other 4, we purchased them all the same day at 2 days old. Her comb and ?flaps (don't know the technical name of those)? are smaller than the other buff. Should I be worried and get ready to introduce her to the gumbo? Rents due - eggs or meat. LOL Thanks.
