as to the worming situation:
The worming food I used doesn't need follow up, it is specifically designed as a 10 day course of feed, which has been fully consumed, as prescribed by both my vet & the farm from which I bought by chickens, they are only available in the UK with a vets prescription. Manufacturers description below.
A highly palatable feed with 17% protein, and also a complete medicated compound for laying hens. It acts as a
10 day wormer for all poultry and is effective against gapeworm, large roundworm, caecal worm, hairworm and gizzard
worm. 1.2kg of Flubenvet medicated pre-mixture added per tonne, gives 30mg/kg Flubendazole in the finished feed
as a broad spectrum anthelminti.
But the good news is, that I have mixed cat food, with growers pellets, with the seed mix scatter & suet pellets & Mrs speckledy is wolfing it down
Edit - Ksane, whilst de worming, I only fed the deworming pellets, as instructed by the vets. Did it that way as was advised by both vet & farm from which we got the chickens that it was the easiest way. was done when we lost our original chicken about 4 weeks ago & when Mrs Speckledy became ill she was checked for worms - it's not the reason they are losing weight.
