Easiest way to count chickens is at night while they roost. That's when I count mine. I count my ducks after they've come in from free ranging, a task in itself because they don't roost. I corral them an let a few at a time get pass as I count. I've had the occasional "Where are they hiding?" situations but always found them before my bed time. My 2 guineas were raised with chickens but now reside with the ducks, they go to roost at dusk.
Egg production has gone from nearly 30 daily to 7-14 for hens, I get 1-2 duck eggs out of 12 and it looks like a pillow factory exploded between coops and pens. My hens usually pick back up between Christmas and mid-Jan but hopefully a few older pullets will be laying before then.
I currently have 41 chickens including 1 rooster and 40 hens with 1 hen being a 7 month old CC Broiler. The Broiler and 3 other hens they can't be with the other hens, so they stay with the ducks full time, even free ranging with them. There are 10 older juvenile pullets, 16 weeks and 6 younger pullets, 9 weeks that share a large divided coop. And 6 new ones that are about 2 weeks in the nursery. My chickens range in age from 2 weeks up to 6 1/2 years old. My ducks range from 2 weeks to 6 1/2 years. Then there's my male duo guineas.
So all together I have 65 chickens, 2 male guineas and 25 ducks, plus a pair of 2 week old ducklings that actually belong to my boyfriend's grandson who lives in another state but I get to caretake them. The chicks and ducklings share the same brooder for now.
My current set up - plus now there's a full garden next to them. There's a total of 6 coops, one is divided and 4 pen areas plus. Photo was taken May 29th, 2023 before I'd gotten or hatched some of the babies. Our setup spans about 65ft across and goes 50-70ft back which includes usable garden area for off season. Dog kennel is 15x30.
