I have 4 barred rocks - have had 1 soft egg out of one of them in the past week. We had some strong winds and heavy rain come through last night. I keep them in the coop of course but the wind was knocking down branches and such. I live in FL so it's not the snow or cold like other areas. Thing is they usually lay after 10am - this morning I went to open things up - the front of coop is hardware cloth - but I put a door on it for bad weather. I noticed 3 eggs NOT in the nesting box. 1 was normal - 1 was soft and 1 looked undeveloped - yolk and white and an extremely thin shell. All the eggs were under their roost Is this normal for them? They are 23 weeks old - should I add oyster shells? They do not free range and have been on layer feed since 18 weeks old. I did manage one day to get 2 normal eggs out of the 4 of them. Could it have just been the storms stressing them last night??
