currently i have 25 hens, not all are laying, maybe half..... i have a community nest box which is 16" high x 16" deep x 4' wide, originally built for 10 hens. why didn't anyone tell me that chickens were so darn addictive!!!!!!! sooner or later most if not all the hens will be laying. will this nest box be big enough for all 25 hens. should i build another one? the reason i'm asking is on a couple of occasions i've found 1-2 eggs out on the coop floor & once on the poop board. no big deal.... yesterday i found only 4 eggs in the nest box and 6 eggs all in the same back corner of the coop floor. is this enough reason for concern?
