Argh! My 13 day old Buff O's were fed laying feed for 36hrs. Now I see that the high calcium content can be major badness for them. I have gone back to the chick starter (and will continue them on it until 18-20 weeks) and added 5 drops of poly-vi-sol to thier 1/2 gallon watering font. They seemed not so interested in the laying feed (I had crushed the pellets) and a few of them had poo changes from a soft uniform poo approx 3/4 of an inch long on average to a less formed poo with larger grain chunks in it. Is recovery likely? (Clearly I am not going to be chicken mother of the year...)
