Hi everyone I have four 6 month old hens and 6 14 week old pullets of various breeds. Over the last 3 days I noticed a sharp decline in egg production. My hens usually lay an egg a day each. Two days ago I only got 2 eggs instead of 4 and yesterday and today only one egg. So I started looking for clues. It has been raining for a week here so I haven't spent much time with them. I saw one hen and one pullet pass some watery manure. They are all bright and active out in their run with no signs of discomfort. The only reason I was looking for trouble is because of the egg production. To compound this issue I have three new chickens in an isolation pen/coop they cannot touch my established flock but really there is only about 4 feet between the two pens. These isolated birds did turn up "sick" after I got them and I have been treating them with Duramycin-10 because that is waht I had on hand and they seemed to respond to it. Their main issues were diarrhea and respiratory. All birds are on pine shavings in their coops and grass runs. If I have to take a bird to the vet to get a diagnosis for the flock I will. Sorry for being so wordy! ANY advice would be much appreciated! Thanks guys.
