Hi Perkhar
I live off grid so I produce all my electric through solar or wind turbine
LED Lights are available on Ebay for about £5 and will run off a 12v car battery for days as they are only 1watt
I use them in my stables for chickens + my 2 dogs.
Also runs the incubator all spring+summer + lights up the shed when we are lambing
I also use Freecycle in my area as people are always wanting to get rid of old bits + bobs,chicken wire,sheds,feeders are to name a few of what i have collected locally even a used sofa for my outdoor dogs.
When you go to your local feed store ask if they have any damaged bags,i bought 2 on friday for £7 when i weighed it I have 48 kg,so the bag didnt loose much.
I have a guy local who makes garden furniture,I buy all the shavings from him for a few quid also sawdust.
Prevention is better than cure when it comes to red mite,so I use Poundland Vaseline type cream on the perch ends and underneath,I find they get trapped in it if they are around.
In the spring summer I cut large bunches of nettles,let them die down for a day or 2 then hang for the birds,they love it + its free.
Also if you have surplus eggs and a cockerel in with them sell some as hatching eggs,you will get more as hatching eggs than eating eggs.
My favourite that I use all the time is if you have a local bookies go in and ask for all the old papers,racing post etc,good for shredding for nest boxes and great for young chicks in brooders.
