I have approximately 50 chickens, 30+ hens, 6 roos, and the rest youngsters. They all went into a major molt, so I figured that's why I haven't been getting very many eggs, only about 4 a day. Well, the egg laying started picking up in the last week or so, but yesterday I got a big fat zero!!!! I was blaming the chickens until this morning. Today was worming day. I went into one pen and as I wormed each chicken, I put him/her outside the pen. There was an egg in the box, which I figured I'd pick up when I was finished. Pen #2 - worm chicken, put outside, pick up next chicken, worm, put outside, repeat, repeat, repeat ... happen to look up and see dog eating something round and brown! I ran outside the pen and sure enough, it was an egg. The box in the first pen was empty! We spent the next hour making a small door in the doors of the coops. No more eggs for Rusty, although he has beautiful shiny fur and looks very healthy!
