This is the problem with the internet. Hearsay becomes fact almost instantly. I need at least three separate sources before I take something as accurate, especially when online researching.
I see in your signature line that you have been an editor for nearly 30 years. I have to say, I have read several of your posts in multiple areas of the forums and I find them incredibly difficult to understand. Lack of punctuation, run on sentences, and a general lack of cohesion are rampant...
My coop doors are all giving me fits too. Some I have to jam shut with a short piece of wood for a brace. Mostly it's from warping, or hinges getting full of bedding (five of my coops have doors that are hinged on the bottom. What a mistake that was.)
I have a Bantam cross pullet that is nearly a year old and hasn't laid an egg. She is sleek and healthy, and so I am just waiting her out. The term 'late bloomer' comes to mind...
If haven't changed anything about their environment and diet and they all seem healthy, I would think they are just having a break. You could try cooking them a small piece of fish for a protein boost, but other than that patience seems to be key when it comes to hens' laying cycles.
Is he sexually mature? Once my young cockerel reached maturity he just naturally picked up the reins as flock leader. And he is part Bantam and 1/3 the size of some of the hens in this particular flock.
Mine have adjusted to the snow, despite hating it initially. I still throw open their doors every morning and some will plow through chest deep snow to get to the carport where the ground is bare. I reward them with some BOSS to scratch around and search for.
I figure if they have the choice...
I had two hens with scaley leg mites so bad they were lame. I dipped them in a solution of vegetable oil, coconut oil and several drops of tea tree oil. Heated the whole concoction in the microwave until it was warm. I held them in the solution for several minutes, as long as they would allow...
Another point of note is that buying methionine supplements on a small scale is insanely expensive. I can cook fresh frozen fish intended for human consumption and serve it to my chickens cheaper than I can supplement a vegetarian feed with methionine.
Is there power in the coop? If you're losing sleep over it, you can buy low wattage infrared heat lamps (60w) from pet stores that sell reptile supplies. I employ heat lamps when the temperature plummets. With infrared heat, they don't heat the air, just objects, so the chickens can stand...
This is a distasteful topic for some, but a vital part of chicken keeping. I just want to applaud everyone involved on this thread for sharing their ideas, thoughts and opinions in a respectful way.
We use this system. The last time we culled it was just one rooster, as I had been attacked quite savagely earlier in the day. He was asleep when my husband went into the coop to grab him, and he never even woke up. It was completely quiet, quick and humane.
