My kids and I got three chicks this spring for our home schooling family. The first one to start to lay was our barred rock. (These are our first chickens ever) We read all the books we could get from our library coop, I don't remember anything about this. She started laying a couple months ago and has had a dirty backside ever since. I thought this must be normal until this month when our wyandotte finally started laying, her bottom looks nice, clean, and fluffy. I feel pretty horrible about letting it go on for so long. This is my sons favorite animal/pet we have ever had, and that is really important to us. So if you could please explain any tips on what to do for a first time chicken keeper mama who wants to take care of her hen. That would be so wonderful of you! God bless.
