moutain mamma, moutain momma,
you have got to take the time to read this thread. all the information is right here. ( i am saying this in a very caring voice ) if you read the thread your frustration level will decrease.
answer to question:
1. each chicken is an individual so laying is in the birds ability to do so. while a leghorn is known for their prolific laying ability your leghorn may not be a prolific layer.
2. dogs eat poop. will it harm the dog maybe maybe not. if the poop from the chicken is healthy probably not. if the chicken is carrying an illness that dogs can catch then yes the dog can get sick.
3. a chicken is an individual . chickens lay all kinds of egg.
4. moses i have no idea.
5. spurs. yes a roosters spurs will continue to grow. you can trim them if they become to long.
6. aspen leaves i have no idea.
7. heritage breed you can get off this forum. check buy -sell- trade. or go to the breed you desires thread. there is a wealth of info at your disposal within this forum. meat chickens you can obtain at almost any hatchery.
from what i am gathering from the description of your birds sounds as if it is a nutrient issue. sandpaper eggs or rough eggs sounds as if it is calcium issue. the leghorn sounds like same thing and the de-shelved looking bird same thing. it sounds as if there is a feed problem. not enough of this or not enough of that. your birds are very young so a full molt is not likely. with that said, the days are getting shorter and it is getting colder so egg laying will naturally slow down.
bee you posted at the same time i was posting. my answers are a little different but same idea.
