I am really hoping with all the knowledge out there someone can tell me what sex/breed our rather large chicken is! We found 3 chickens at the side of he road and took them in. They are about 6 months old now and were about 4 weeks when we found them. Last week we introduced 3 ex battery hens. 1 of the original chickens (who we had doubts about) turned out to be a definate cockerel (large comb, crowing all the time, prancing about and mounting all the others), a local sanctuary took him in as we have neighbours and as much as I loved him he was so noisey and wouldn't leave the others alone. 1 of the originals is definatley a hen as she laid her first egg yesterday. The other Fatso is the problem. She/he is huge, and is making a really ugly deep crowing noise, usually just a couple of times in the morning, she/he is mounting the others, and pecking the back of the necks but is displaying no other cockerel tendencies. No dropping of the wings or prancing about like the other one. You can pick Fatso up and it's really friendly. I have photos but not sure how to upload them. We have no idea as to the breed but think it's mixed, the other hens are Goldlines and Exchequer Leghorn. I really need to know what he/she is as she is virtually assaulting all of them! Fatso has also pinned them to the floor with her foot which is a bit distressing for them. but now he/she is wandering around with them as if butter wouldn't melt. Is this normal hen behaviour or do we have another cockerel. Any advice would be greatly appreciated as Fatso is my favourite and I really don't want to see he/she go.
