I have 7 Rhode Island Red hens and 1 rooster. There feeding is fine and it is not a pest getting the eggs. I have not seen an egg in 3 weeks. I live in southern indiana. For about a month in a half i have had my ducks in the same coop (only at night), they get along great, but could the ducks have an effect on the chickens lay?? For the past 4 nights I have kept the ducks out...they have not started laying, but could it take a little time to start back up? About a month ago I fed them some patatoes...... I wash out the coop every day now(i just spray it out because its a tile floor) I also keep up on food and water. they started laying about 2 and a half months ago and then 3 weeks ago the production came to a complete stop! They are soo sweet still, even the rooster! Please Help!!!
