I have 4 aracauna hens and they layed 4 green or blue eggs and then have not layed another for 2 months than just now layed one but it is cream colored. why is that? will what i feed them change the color? and it was smaller than the ones before and only 3 were layhin out the 4. so i think the other one started layin cause that is what the other 3 done at first, they layed lil small cream colored ones than they were blue but now im getting none from them except the lil samll cream one yesterday? can anyone offer some in sight to maybe why they have quit?
