The MSPCA at Nevins Farm is offering a lecture titled “Starting Your Own Backyard Flock” from noon to 3 p.m. next Sunday in its Rogers Education and Training Room. Topics will include establishment of a successful flock, nutrition and housing, basic handling, and safety. Intended for animal professionals, farm bird enthusiasts, and members of the public, the lecture will be followed by a choice of hands-on learning events at the farm’s chicken coop. Participants need only register for one hands-on session; they are scheduled for March 8, April 6, and May 4. Two $10 donations are required, one to register for the lecture and one for the hands-on day. For more information, call 978-687-7453.
