A Backyard Chickens program will be held on Wednesday, Feb. 12, from 6 to 7:30 p.m. at the Hellam Township Municipal Building, 35 Walnut Springs Road, York. Topics will include the advantages and disadvantages of raising chickens, zoning and laws, housing and feed, deciding whether to get a rooster, waste management, daily maintenance, flock regeneration, and disease and pest management. Information will also be provided about similar animals, such as turkeys, ducks, and meat chickens. There will be a question-and-answer session. The class is suitable for beginners as well as those looking to enhance their existing poultry skills.

Identifying Trees by Bark will be held on Sunday, Feb. 16, from 2 to 4:30 p.m. at the Horn Farm Center. This program will begin with an overview of the science of tree bark, followed by a hike through the Horn Farm's woodlands to explore field identification of various tree species via bark. Other wintertime identification features, like twig arrangement, buds, and leaf scars, will also be addressed as example trees allow. The class will take place entirely outdoors and will require lots of walking on hilly woodland terrain.
