They certainly can be frustrating to catch once spooked! They are very trainable though and will quickly adapt to feeding. Cracked corn is a favorite and you could probably get 1 or 2 more in a Havaheart trap baited with the corn after they have been trained to expect it. Once the hens are mature, you should begin to see eggs on a regular basis. They can be pretty random but always are laid in the early morning typically by 9AM. Best to collect them to prevent a hen from getting broody and trying to hatch them. They are excellent eggs for baking.
