What is the best food / thing to do, to get my pullets fattened up quickly? I have 10 Amber Star 'looking' chickens. They are about 12 weeks old. They are still growing and I was intending to eat them.... but they are so thin. Is this breed naturally thin? I have roosters and hens.. all are thin. My partner is getting mad as these chickens are always getting into the house and pooping everywhere!!!! They are TOO friendly and mob anyone who comes into the yard. They are getting to be a problem and its way past the time to put them in the freezer. They are fed mix flock feed (which is says on the bag is for ducks, chicks, and non laying chickens. They also free range all day and can range over a large area to get insects and greens. I give some greens each evening to get them into the coop. They are very healthy and energetic, but don't seem to be putting on any muscle. I can feel the breast bone in all of them.. and they have no meat on their thighs. They feel heavy though.. but no muscle or fat. Do I just need to wait longer? Or is there some low cost food I can feed to get them fatter? I can't keep them more than a week or 2 at most.. I keep promising my partner they will be gone on a certain day (but the days keep going by)! Do you think buying feed for broilers is a good idea for them? I don't want to spend lots of money or waste time boiling up my other chickens eggs for them.... or it will end up the cost is not worth raising these chickens.
