Slow egg production

Hello just wondering if any one has any ideas please.
I have 1yr old chucks that have laid on and off through the winter then for the last a couple of weeks  they were laying an egg each per day even though Rocky the road island red still has tail feathers to come after her moult,This week and last only one of them is laying every couple of days,is this usual
Also
Treacle the copperstar is looking as if she has started to moult again,feahres all over the run the last day or so,she appears happy and chatty enough and is eating well.she had a moult before Christmas,do they have mini moults??as this is the only reason i can think she has stopped laying.

many thanks for any ideas

Hello joyful,Nope she is not looking broody,pottering about being nosey and not hanging about nest box.
They only lay in the nest box or in corner of the shed if there is no room in the favoured box.
They are on layers pellets and fresh greens,mixed seed and shell as at the mo they are banned from the garden.

hello casey
thanks for the reply,just been up with chucks to check them all over,Treacle is moulting quite a lot today but quite happy-added vermx to water just in case and a bit of tonic,noticed red mites tucked in at end of perches so i will wash the shed out  next weekend -weather permitting enough drying time!
No sigh of parasites on the birds,so its probably just me worrying to much.

I notice you are over in Alsace,lucky you,hows your weather?I think i would much rather be chuck raising in our Brittany garden

Thanks Joyfull,i will wash shed out tomorrow methinks instead of the weekend and douse the blighters
