Hey all! My problem is this... I have three hens, a road island red, a Plymouth Rock, and my beloved isa brown. I feed them a quality high protein pellet with the occasional treat here and there and of course good fresh water everyday . My rock and red give me nice big eggs almost everyday. My isa on the other hand, nothing! Now she was my first layer (3 weeks before the other two,) but about 3 weeks ago she just stopped. Haven't seen an egg since. I don't think it's their diet, she eats well and does not appear sick. Is she just a dud of a hen?
