My 6th grade daughter needs to do her science fair project. We are hoping to find something to do with our chickens and/or eggs. We have 6 hens and no rooster. All 6 hens are laying - we get 5 brown and 1 muddy/green eggs. She has to do a hypothesis and a conclusion along with all of the other stuff in between. We have approximately 4 weeks to do this. Any ideas? Thanks!
