i have 6 chooks. a couple of weeks ago, i took them to the usual place for boarding for 8 days. while i was away 1 of my chooks died. the farmer added another to the flock without incident i collected them last tuesday, and since then have had no eggs at all. this is strange, because before they went away the 5 surviving chooks were all laying regulary. they did come back to a new run. my son extended their run so that they could stretch their wings. one of the birds is molting any reason, do you think, why i have had no eggs at all since tuesday?
