i am new to chicken keeping, although i had them with my family. i recently took time to build my own chicken house, with run..careful to make everything perfect for them, fox proof, perches, weather proof, sizes etc.... have been looking for chickens, was going to get rescues, but then today i went into a nursery and bought 3 for £15. here is were i have been irrisponcible, which is actually very unlike me..... they are young, but i dont know how old, i have no idea of what sort/breed they are....and worse no idea what sex they are....i know i am an idiot so please dont hate me, i have beat myself up over such a stupid decision...... now i am looking for advice. how can i try and answer the question of sex, breed and age? thankyou in advance.
