Hello and welcome
I am very new to chicken keeping and I have Silkies.
Mine were hatched in an incubator in my kitchen last year.
I have found tons of advice on this forum so no doubt everyone will chip in. I give my Silkies mealworms as they need protein but there’s no bugs in the winter.....(they’re free range) and some fruit and vegetables.
I have a small electric chopper in the kitchen and my girls like apple (no seeds) pears, carrots, lettuce and if I have leftover peas they love those.
It snowed last week so they had warm porridge.
I don’t make it hard work, they just get whatever is in the kitchen and whatever is left........bread too. This doesn’t make up their diet I hasten to add.....it’s a treat.
Nothing mouldy, and no citrus.
Cut a cucumber in half and see if they’ll peck at that.....or a head of cabbage. There’s a list on here of food that is suitable. Someone will post it, they’re very helpful.
Good luck
