I have recently ventured into keeping chickens (for eggs) and have bought 4 pullets POL. We have a Wellsummer and 3 light sussex, i spend hours just watching them.
Despite the plan just to have 4 in an ark we decided almost straight away to make them a much bigger run (fencing 1/3 garden for them) so they can be as 'free range' as possible and stay safe from the dogs.
Of course more space means we are loking for a couple more to join them ;D but until the newbies arrive here are our current girls......
