My three EE girls are 25 weeks old and two of them (Mabel and Ethel) have had bright red combs and wattles for weeks now. Just this morning I've noticed the third (Mamie) is getting 'red in the comb', but no sign of eggs! I haven't noticed any squatting or other signs (is there really a laying song they sing? ) so does this mean I should start searching our yard/woods for hidden nests? It's over an acre so I'm definitely not looking forward to fine-tooth combing that big of an area!
