Smart Feeder - Light sensor values

[clucker1]

My 4 omlet girls who are 18 months are doing softies every other day or so for the last 3 weeks. I am trying to work out the cause. They are on layers pellets and for the last 2 weeks have had oyster shell and cod liver oil added to their feed. Help needed please... could it because

 

they have got 2 newbies in a rabbit hutch opposite them who have been there 3 weeks or

they are having a mini moult (the occasional feather is left around and I understand it is the moult time)

their treats (kitchen s"Ooops, word censored!"s) which they have always had a small bowl full is upsetting them

 

Any other ideas? They normally free range for a couple of hours a day. Thank you.

Another thought I meant to note is the girls have had their feed stations reduced by half as I have given my other grub to the newbies ie my old 4 girls have just one grub now between them. Presently waiting for a new grub to arrive from Omlet, meanwhile have today added an old tin for them to eat out of, hopefully they won't knock it over.

probably the moult. yours are too young to have given up laying all but softies, and they'll be eating enough. mine stop laying altogether when moulting, so yours are trying to do both.

Thank you for that. Any idea how long the moult will last for?
