Interesting weekend

Well today my 3 had me at it 

No eggs this morning, none by midday, then there seemed to be a scrabble to get in the nesting box. Beryl was sitting and making her "do not disturb noises" and the other two were harrasing her. So I shooed Sandy and Hen out of the run and shut Beryl in. The reaction of Hen and Beryl was amazing they were attacking the coop and run where Beryl was sat, just like you see vultures on TV. After a few minutes I tired of this behaviour and consigned Sandy to the dog cage. What a good investment that has been

With sandy out of the way Hen became her usual amiable self and all was peacefull until Beryl announced to the world her had egg

I then let her out and Hen went in a bit later, as usual, and produced, but without the foghorn

Both shells were good, as both hens were now out and eggs safe I released Sandy soft shell, who walked down the garden then straight into the coop for a look see. So I know who the egg eater is now. Yesterday lunch time I had found dried egg yolk in the nest box and a pale broken shell in the run when putting them to bed.

When Sandy had laid a shelless the other evening I was too slow to get it up before the other two Beryl and Hen had started eating it. Is it true a hen will not eat her own egg, as this seems the case here?

I think the future for Sandy the sinner is quarantine till the others have laid and I am busy. She will get to know that dog cage very well

Up until couple of weeks ago these birds were giving me 3 eggs every morning day, so reliable.
