I have 20 chickens right now: 7 pullets, 7 hens, 3 roos, and 3 cockerels. They're in 3 kind of awkward groups right now, to be rearranged for the winter into a main flock of 2 brother roos with the ladies and bachelor flock of 4. I count my chickens each night, but my biggest roo can apparently still fit more than one cockerel in his abundant neck floof when it gets chilly...so sometimes I have to look for extra sets of feet to make the numbers add up lol.
