I have several questions, and comments!! Does anyone keep your eggshells and crush them and feed them back to your chickens?? If so, what's the procedure?? I have heard to boil them and then crush them up?? Also, I have been marking the fresh eggs with the date, with a perm marker! They are brown eggs and I didn't think a pencil would show up, and an ink pen didn't seem to work! What is the best way to mark the date on them, and will it be harmful if I feed the crushed shells back to the hens??? Do hens "come in heat" like dogs, cats and other animals??? And what do you call it?? I had a NH Red that would take a few steps and then just sit! She even limped a little. She liked me to pet her back! I was afraid something was wrong with her!!! The next day she was better, and the next day she was back to normal!!! This is different than "broodie" isn't it?? She didn't try to peck me!! Isn't "broodie" when the hens want to sit on eggs to hatch them??? I was thinking about getting a plastic toolshed for a chicken house 7X7 or 8X10! Only I couldn't figure out how to cut a little chicken door in it. I wanted to put it outside a chain link 10X10 dog run. I hadn't figured out how to cut a small chicken door in the chain link fence either?? I wanted a regular door available in the fenced in area and also the plastic house! Maybe this idea isn't do-able!!! The plastic toolsheds would be warm, and have the plastic floor which would be easier to clean!! Is plastic housing not good??? Right now I have my 6 guineas and 5 pullet hens in a covered 10X10 dog run--sitting on the ground, with tarps on all sides for warmth and to keep the rain out. It has gaps at the corners where the tarps are tied. I left the bottom 2 ft. bungie corded, so I could raise it up when the weather was nice outside. I cover the 2 large dog kennels that the chickens sleep in at night with tarps (grill covers) to keep them warm. I have the two kennels with doors on them so I can lock the chickens in at night to keep them safe!! I am covering the door with another tarp!! In the daytime I take the grill covers off and put smaller pieces of tarp on the top to keep the poo off the kennels!! I was trying not to spend alot of money, but have spent alot more than I planned!!! I do let them free range most days, unless it's rainy and cold! My guineas have been wandering away to the neighbors, which I don't like!! I have to go get them--call them home!! I don't know if there is any way to prevent this??? They are so curious and like to follow people or animals or cars around, but I'm afraid the neighbors' dogs will get them or they will be a nusiance!!! Any suggestions would be greatly appreciated!!! It's been a learning experience and alot more work than I thought!!!
