The best way to discurage yourself from hatching is too look at the numbers.
How much coop space do you have, how many chickens do you want in your flock, how many groups of different age chickens do have to intergrate, if you are not going to keep the chicks you hatch, will you be able to find homes for them, ETC, ETC, ETC.
If I had my way, our family would be hatching all year round. I am bound to do 2 more hatches this season and then be done for the winter. Once my husband and I pondered the answers to the above mentioned questions, we decided it was time to stop hatching.
Hatching is the fun and easy part. It's building more coops and intergrating new members into the flock that is hard.
