I have had a few chickens given to me that I've raised from just a few weeks old and was told they were all ladies. One we thought started looking like a rooster because it was always so much bigger compared to the others. That friend came around and said it was definitely a girl. So we named her Lola like the song by the kinks. Now I am doubting if she really is a she. Lola is so large, Is a bit over 7 months old. Doesnt really show dominance yet and gets put in "her" place but the other older chickens we have. What really makes me doubt is we thought we heard one of them crowing this morning or attemtping too. Wasn't a full crow. Any help would be appreciated. Photo hopefully is attached.
