Oh Kye thank you so much.  That information has helped to put my mind at ease.  My new chucks have been pecking away on them all afternoon, completely ignoring the corn feed I put in for them!

Any left over naturals from the kitchen (veg) can be boiled and mashed, you don't have to spend money on special foods.

'Morning surfingdevil,
We just love our little chucks to bits.  They are friendly, fascinating pets and so easy to keep.  We got them from the market in Palma last summer and for a while we thought we'd got duds as it took them weeks to start laying.  But then, one day, there was a small, brown perfectly formed egg in the nest box!!!  Now they each produce a huge brown egg every day (we have three girls - Betty, Dot and Dora).  We bought a chicken house on line from Amazon and had it delivered here and built a compound for them.  However, the lower garden is such a shambles at the moment that we let them out to free range every day.  This is until we get the veg plot sorted out and planted, then we'll have to find a way of keeping them off the new shoots!!  We live in the beautiful village of Es Capdella and get our hen food from the pet shop in Calvia.  Whereabouts are you?  Good luck with everything.  Let us know how you get on.
Happyhenlady, Es Capdella.
