Here's our chicken math, started with 12 pullets in April, in June a fox killed 8 of them. Bomgaars still has chicks. I think nice we'll replace the 8 we lost, you know grow the flock by a dozen a year. Besides it will help the 4yr old stop asking what happened to my chickens.
My husband says "I was thinking more like 40". We got 36 pullets and 4 Guineas
His dog kills one of the 3 polish (his favorite), he orders a dozen straight run polish off the internet. That was end of July. Two weeks ago they arrive, the never had an issues before, dogs get into the temp. brooder within 2 hrs of arrival and eat all of them.
I get 6 EE and 6 American (I want the blue and green eggs) thinking we already have a brooder why not, oh but they can order a dozen assorted polish pullets. Happy early birthday honey...
I started with 12 birds in April its September and I have 58 layers, 1 rooster, 3 guineas, 48 Cornish cross to be butchered at the end of October. The rooster probably won't be with us much longer.
