hi, I have had my chickens since a week before Easter. I believe my chickens are about 20weeks old. I have 3 Rhode Island Reds. I was very surprised to walk out yesterday and clean their coop to find an egg sitting in the nest. Today I went out and found a soft shelled egg. I popped it open and there were what looked like 2 deep orange yolks and 2 fuzzy light yellow (looked like almost chicks). The egg from yesterday was just a beautiful normal egg, but after this mornings findings we cracked open yesterday's egg and sadly it was wasted I am not certain that all my chickens are hens, I also don't know what to make of this situation. I feed my chickens good food and calcium, we hadn't even started with the later feed bc we didn't think they were ready. Are my chickens too young for eggs? Why did she start laying? And do they start to mate this young? Any help is much appreciated!!!
