I have 3 EE cockerels around 5 months old. 2 of them are starting to show signs of trying to mate...I think. They will grab a hen by the neck and kinda sling her around a little. Not too agressive.....they dont try to get on backs yet. One of them hasnt started crowing yet and is not showing any signs of being ready. In fact, he prefers to be alone and is quite the loner while they are free ranging. Due to getting more cockerels than hens when I purchased, I only have 3 hens (2JG and 1 EO) that are the same age, but they were not raised together. I realize this may cause problems. I have 16 chicks that are 3 weeks old that are supposed to be pullets. I am hoping that this situation might correct itself in the spring. Don't things slow down in the winter?????
