In the spring I ordered 4 chickens and have been raising them ever since. Last week one of my 'ladies' started crowing and so we had to find him another home (out on a nice farm instead of here in the city...). I kept telling my husband- it cannot be a male because it looks just like those other two.... I think we have 2 more roosters How can you tell? I picked up the smallest one we have (I think she is a chicken...) and was trying to see if I could find her vent. What does it look like? Where is it? Is that a good way to determine if it is a female? They are almost 23 weeks old and we have not seen any eggs (they are silver-laced Wyandottes). I am getting very concerned that we were sent all roosters. Any help in figuring out the sex of chickens would be great!!!
