There was a dilemma with my two chickens... For a while I was convinced they were both roosters, then only one rooster, now... ONE is def. a hen Found 1 egg Aug 1. Now since then (10 days later) I have only seen 5 eggs (2 of which were broken on the floor of the coop). It has been 5 days since I've seen an egg. They are 18 weeks old. As far as I know, only one is laying. Recently switched their feed from starter/grower to layer (bad idea?) and cut back on poultry treats (Product of Omega for poultry). Are they stressed? I haven't seen signs of parasites. Is this normal or should I change something in the coop.
