They are probably not "worth it" when accounting for the care required, but I get feed for about $20 a bag and a scratch block for $20 every 3 months or so for 4 chickens who generally give me an egg/day each. 4x30x3=360 => 360/12=30 dozen eggs so that works out to less than a dollar per dozen which is below market cost 5 years ago.
