I was wonderfully gifted 60 chickens about 7-10 are roosters only keeping 1-2 for fertility rest I am butchering. Hens were laying 9-14 eggs a day (from flock not each) suddenly stopped all together as if overnight. I know a dog made it into the pen and spooked them I fixed that problem but they were still laying for a day or two after but there is a big ruckus at night over who sleeps where and how lots of perch space but about 12 hens on the ground huddled up won't use it. I know I have to many but which do I keep? I want about 14-18. Not sure how many my facility will hold. I have a 7X9X8 coop with 12 laying boxes and 18 feet of perch. The range pen is a 20 ft by 10 ft space with 24 ft of perches fully enclosed with flight room if they so choose. Most of my hens are 1-2 years old none older than four I am told and some the black ones they are all mixed bred are I believe 1 yr or less they have bald bright red bottoms from mid back all the way down past their vent and between legs. Other hens are fluffy and beautiful but have thicker shanks and I assume are older. I want them to raise chicks for new layers and butch each year but how do I select who to eat and who to keep? Thank you for any input you can give me I really need the ladies to start laying again!
